Each change to the cohort is logged here with the date and reasoning, so anyone bookmarking or citing this page can see the state at a given time.
2026-07-15The typed 3PL tier went live: seven third-party logistics operators with verified FBA prep lines are now hosted, typed listings (Ship Depot in Palmdale CA with published $0.30 to $0.55 per unit prep, Shipping And Handling in Jacksonville FL with real press corroboration back to 2012, PFC Fulfillment in Camanche IA named a Multichannel Merchant Top 3PL in 2023 and 2024, Jay Group of Lancaster PA established 1965, Save Rack in Boca Raton FL, iLogistics USA in Miami, and Shipping Pilot in Middleburg Heights OH, whose paid-syndication media badges we disclose and discount). Each cleared a typed standard: real entity over 12 months, live maintained site, a substantive prep service line rather than a keyword page, and a working contact channel, plus the same fabrication screens as every listing. Full 3PLs are never ranked on this page and never counted in prep-specialist stats. The same wave rejected two 3PLs whose prep pages were keyword bait or whose operating entity effectively did not exist, and held one on fabricated tenure. The /fba-prep-3pl/ page now leads with these verified listings; its national-platform recommendations remain clearly labeled as unverified outbound. Directory: 100 verified prep operations plus 7 typed 3PLs. Curation and honesty over volume.
2026-07-15Later the same day: added four prep specialists the machine classifier had mislabeled as 3PLs, caught in a reclassification pass and verified under the full 4-point standard: Flatwillow Prep and Ship (Laurel MT, family-run by named owners, per-unit card from $0.70 at volume, the shared Montana coaching-program rate template disclosed and the operators confirmed distinct), Central MT Prep N Ship (Montana, family-owned since 2019, $0.90-$1.00/unit, its 30-day inventory-forfeiture clause flagged plainly as the shortest window we list), Frontier Prep N Pack (Montana, since 2023, corroborated by two independent directories, form-only contact flagged), and Preppal (Virginia, wholesale prep from $0.75/unit, listed state-only with its thin published footprint stated). The same pass held three: a New Jersey operation whose about page claims eight years and five million units against its own one-year, thousand-a-week counters plus an unverifiable Pfizer-vaccine executive claim; a Montana shop with no reachable contact channel at all; and a six-month-old North Carolina startup on the standard new-business re-check. The directory now spans 100 verified centers, a milestone we mark by noting that eight of the candidates we vetted tonight alone were rejected or held. Curation and honesty over volume.
2026-07-15Added the directory's first three explicitly typed multi-service operators, each prep-primary with real fulfillment lines alongside and each cleared through the same 4-point verification as every other listing: FR-Logistics (Doral FL, active Florida corporation with a named president, an audited Amazon SPN service-provider listing, and a dated 2026 rate card from $0.55/unit FNSKU, with its older conflicting prep page flagged plainly), FBAZoom (San Diego CA, the FBA-facing brand of Momentum Warehousing, disclosed as one operator with two names, publishing unbundled per-unit rates of $0.35 inspection plus $0.20 FNSKU), and West Coast FBA Prep (Mission Viejo CA, the prep-branded arm of a press-covered Orange County 3PL, with a fully public card from $0.99/unit). Every listing now carries an explicit operator type (prep specialist, multi-service, or full 3PL); the ranking on this page stays limited to operators verified under the prep-primary standard, and general 3PLs are never ranked. The directory now spans 96 verified centers. Curation and honesty over volume.
2026-07-14Added 27 verified centers in one day, the largest expansion since launch, from the first full pass over our completed candidate map (81 mapped candidates plus a same-night discovery sweep, all vetted by parallel evidence review plus editor judgment). New US listings: FBA FlexPrep (Houston TX, since 2016), Fast and Forward Prep Center (New Port Richey FL), Prep Center LA (Commerce CA), Prep Center NJ (South Plainfield NJ, mandatory $59/month software fee disclosed), FBA Prep NY (Westbury NY, weight-based matrix from $0.49/unit that sits well below the US median, which we flag), TurnKey Prep & Ship (Michigan books-and-media specialist), PrepFBA (Vista CA, since 2017, address corroborated across three directories), Schellstede Shipping (Santa Fe TX), thirteen Montana operations across Billings, Great Falls, Red Lodge, Huntley, Lavina, and Pompeys Pillar (including book-prep specialist Big Sky Prep N Ship and Magpies Prep and Ship with its dated PDF rate card), and FastFlow Prep (Linden NJ). Five international centers joined off this US ranking: PrepCenter FBA (Germany, Impressum and VAT verified), Scendr and Ecommshack (UK, both Companies House verified), FBA Prep AB (Alberta), and North Prime Prep (Toronto). The same pass rejected an AI-fabricated site created three and a half weeks ago on a recycled domain, rejected two sites with fabricated or template testimonials, rejected a Montana site claiming twelve years of history on a ten-month-old domain, routed twelve multi-service 3PLs out (one serving injected casino spam from a compromised homepage), held a UK operation whose claimed Ltd entity has no Companies House registration, flagged one candidate whose pricing page emails a different published center (a connection we are investigating), and held over twenty young, closed, or unverifiable operations with dated re-check triggers. We cross-compared every Montana candidate for clone networks: the shared contract language across several is a seller-coaching-program template used by distinct operators, disclosed on each profile. A same-night discovery sweep across new search modalities then confirmed the map itself: of 136 additional candidates surfaced, 121 were already in our vetting universe. The directory now spans 93 verified centers. Curation and honesty over volume.
2026-07-06Added Steadfast Prep and Pack (Great Falls, Montana), a newer tax-free prep operation registered with the Montana Secretary of State in May 2025, with an all-inclusive published card from $1.00/unit including 30 days of free storage. It came in through our operator application and cleared the 4-point verification from primary sources; we list its age and its zero independent reviews plainly, and its Walmart WFS claim as operator-stated. The directory now spans 66 verified centers. Curation and honesty over volume.
2026-06-16Added Urva Prep Center (Newark, Delaware), a multi-service FBA and Walmart WFS prep operation founded 2022, running a 25,000 sq ft tax-free facility at 301 Ruthar Drive plus a 10,000 sq ft site in Bear, with public volume-tier prep pricing from $0.70 down to $0.55/unit wholesale. It came in through our operator application and cleared the 4-point verification from primary sources. We confirmed the 301 Ruthar Drive address is distinct from the unrelated Newark prep cluster on Executive Drive and 310 Ruthar. The directory now spans 65 verified centers. Curation and honesty over volume.
2026-06-10Added 3 more verified centers from the discovery refill: EnZone PrepWorks (Conroe TX, dated public rate card from $1.20/unit, registry-confirmed owners), Live Free or Die Distribution (tax-free Rochester NH, NH SoS good standing, from $1.00/unit at volume), and Tailwind Pack & Ship (tax-free Billings MT, from $0.50/unit at volume, listed with a warning covering a 90-day inventory-forfeiture clause and a transit-liability disclaimer). The directory now spans 63 verified centers. Three candidates from the same pass were held rather than listed: a 6-month-old Louisville site with an apartment-street address and seeded testimonials, a Colorado operation whose current activity we could not confirm, and a Manchester UK company whose site has been frozen since 2021 with a broken contact link. We also published our UK ranking at /best-fba-prep-centres-uk/. Curation and honesty over volume.
2026-06-09Added 5 more verified centers after a root-homepage verification pass: Kitting & Assembly Solutions (Commerce City CO, since 2014, quote-based, 20 public Google reviews), FBAPrep4U (Gahanna OH, flat $0.90/unit wholesale-only), Montana Logistics Pro (tax-free Great Falls MT, public tiers $1.45 to $1.00/unit), Lulux Fulfillment (Long Island NY, 25% of each ASIN's FBA fee per unit, listed state-only because the operator withholds its street address), and Central Virginia Prep (Waynesboro VA, used-books specialty, listed with a warning for broken site navigation). The directory now spans 53 verified centers. Two candidates from the same pass were rejected: a UK operator running roughly 50 programmatic US state pages with no US facility, and a cloned site carrying a false tax-free claim for its Virginia address. One Brazil-facing hybrid is held pending identity questions. Curation and honesty over volume.
2026-06-03Added 4 more verified centers, promoted from the candidate universe after a root-homepage verification pass: Prep Center IN (Plainfield IN, tiered per-unit from $0.55/unit, no minimums), Simple Price Prep (St. Marys GA, family-owned since 2015, public per-service rate card), Oregon Prep and Ship (tax-free Sisters OR, since 2022, FBA plus 24-hour FBM), and Marketplace Prep (Fort Worth TX, since 2020, FBA prep productized down to $0.75/unit with public Trustpilot and Clutch reviews). The directory now spans 48 verified centers. Two candidates from the same pass were not listed: a clean prep-primary New Jersey operator under a year old (held until it crosses the 12-month bar), and a Philadelphia site that failed verification on fabrication (a 2026 domain claiming a 2018 founding, an address that maps to unrelated businesses, and recycled stock testimonials). Curation and honesty over volume.
2026-06-02Added 4 more verified centers, all leading with FBA prep: Rater Prep Services (Gahanna OH, public rate card from $1.00/unit), Simply Ship Now (Jacksonville FL, per-unit prep from $1.50/item plus disclosed done-for-you retail-arbitrage sourcing), Romex Enterprise (Cape Coral FL, an Amazon returns and removal-order reprocessing specialist since 2008), and Prep & Store Center (Ohio, prep plus storage since 2014). The directory now spans 44 verified centers. Several universe candidates were not listed this round: general fulfillment 3PLs whose Amazon-prep page is one of many service lines (routed out), a package-forwarding hybrid and two prep centers with no confirmable city (held for operator confirmation), and a stale low-volume site (held). Curation and honesty over volume.
2026-06-01Added 4 more verified centers, all promoted from the candidate universe: Boxy Prep (Hastings MI, from $1.10/unit), MI FBA Prep (Lapeer MI, since 2017, $0.85 to $0.90/unit), Ready Set Prep N Pack (tax-free Helena MT, $1.25/unit), and New Jersey Prep Center (Hainesport NJ, from $0.55/unit). Each leads with FBA prep and clears the operating, liveness, FDA-when-claimed, and manual-review checks. The directory now spans 40 verified centers across 20+ states; we continue to route general fulfillment 3PLs out and hold sub-12-month operators until they cross the track-record bar.
2026-06-01Added 4 more verified centers, all promoted from the candidate universe: AZ Prep Center (Tempe AZ, per-unit from $0.88), Kaizen Prep Services (Miami FL, since 2018, quote-based), DM Prep US (Libertyville IL, full rate card from $0.45/unit), and Cajun Prep (Kentwood LA, since 2020, $1.00/item, waitlist). Each leads with FBA prep. Several more universe candidates were not listed this round: general multi-channel fulfillment 3PLs where prep was a sub-service (routed out), and generic prep sites that never mention Amazon or FBA (held as unclear). The directory lists FBA-prep-primary operators with a real track record.
2026-06-01Added 4 more verified centers, all promoted from the candidate universe: FBA Champs (NJ, tiered from $0.45/unit), Priority Prep (Tyler TX, since 2017, 2-day guarantee), Esellts (Richmond VA, volume-tier down to $0.30/unit), and Flat Rate Prep (Madison WI, since 2016, one flat $2.25 all-inclusive rate). Each leads with real per-unit prep pricing as its primary offer. Several more universe candidates were not listed this round: general 3PLs and DTC-fulfillment houses where prep was a sub-service (routed to 3PL), and one clean prep center under a year old (held until it crosses the 12-month operating bar). The directory lists prep-primary operators with a real track record; everything else routes out or waits.
2026-06-01Added 4 more verified centers, all promoted from the candidate universe after primary-source verification: Number One Prep (Doral FL, per-unit from $0.45), Carolina Prep & Ship (Apex NC, family-owned, from $0.65), United States Prep (Salem NH, tax-free, $1.50/unit, flagged for an early-stage website), and Express Prep Center (Pennsauken NJ, from $0.65). Each leads with real per-unit prep pricing. Three more candidates were not listed this round: one whose website was returning errors, one general 3PL/freight forwarder with prep as a side line, and one ambiguous 3PL held for review. We list prep-primary operators and route pure 3PLs elsewhere.
2026-06-01Added 4 more verified centers: Dollan Prep Center (Newark DE, public rate card, with an honest below-average Trustpilot caveat), East Coast Prep and Ship (Wilmington DE, public rate card across FBA/WFS/SFP/DTC), 406 Premier Prep (Billings MT, public per-line-item card, no third-party reviews yet), and Brown Box Ninja (Temple TX, operating since 2014, tiered prep pricing). Two candidates were deliberately not listed: one whose own website was returning errors (fails the liveness check), and one general 3PL with no per-unit prep pricing held for editorial review. Curation over volume.
2026-06-01Added 4 more verified centers after primary-source verification against the 4-point standard: PrimeTime Prep (Portland OR plus Lincoln NE, public a-la-carte pricing), Proven Prep (Portland OR, 4.93/56 third-party rating), Stock and Ship (Springfield OR, BBB-confirmed since 2021), and Amazing Logistics (Sun Valley CA, operating since 2017). Proven Prep, Stock and Ship, and Amazing Logistics are multi-service operators published with disclosure; primary positioning is FBA prep in each case.
2026-06-01Added 8 verified centers after primary-source verification against the 4-point operator standard: Prep Ninjas (Oregon, family-owned since 2018), Grizzly Prep MT (Montana, third-party 5.0/5), HexPrep (Oregon plus Illinois, third-party 4.90/157), Extra Mile Prep (Alpharetta GA, 40,000 sq ft), Montana Prep Solutions (Helena MT, no fees or minimums), Oregon Prep Center (Portland OR, BBB A+), A&M Prep Services (South Gate CA), and Network Prep (Lafayette OR, currently waitlist-only). The phone-answered-live check was retired from the standard; verification now rests on registry/track-record, FDA-when-claimed, live-site-plus-FBA-keywords, and manual editor review.
2026-05-27Reframed as the dated 2026 ranking and published a companion verification study at /fba-prep-verification-study/ (what we found vetting the candidate universe, with named exclusions). Methodology copy corrected: placement is editorial, not a numeric weighted score.
2026-05-19Added 3 tax-free-state centers after primary-source verification: McKenzie Services (Oregon, women-owned, tiered membership pricing), Heroic Prep (New Hampshire, transparent per-unit volume tiering, 1,000-unit minimum), Delaware Prep & Fulfillment Center (Newark DE, multi-service FBA + FBM + arbitrage, operator-stated SPN). Cohort-2 source doc claims (founder names, capacity numbers, testimonials) were partially fabricated; everything in our published profiles was re-verified from operator-direct primary sources before listing.
2026-05-13Initial cohort published: 3 pure FBA prep centers (MyPrepCenter, WestFBA, FBA In and Out). 15 candidates from amzprep.com archived as non-pure-prep (3PLs or platforms); see exclusions below.
