FBA prep centers in Pennsylvania.

The Swifthouse describes itself as a family-owned, boutique 3PL in King of Prussia, Pennsylvania, outside Philadelphia, and is built around Amazon prep with direct-to-consumer fulfillment and storage alongside it. FBA prep is the flagship and it is priced openly rather than quoted: $1.59 per unit up to 500 units a month, falling through five bands to $0.69 above 15,000, with check-in, inspection, labeling, polybagging including the bag, and shipping all folded into the one rate. A 300-unit monthly minimum invoice applies and is waived automatically in any month with no activity. Both sides carry account setup fees: $200 one-time on the FBA plans, and $600 plus $50 a month on the separate DTC rate card, which starts at $2.50 for the first pick and pack. Card payments add 3%, waived for ACH, wire or check. Storage is month to month with no long-term contract. Two cautions. No phone number is published, so email is the only direct channel. And the four customer quotes on the site are initials-only, with two of them near-identical in wording, so treat them as marketing copy rather than references.

Precision Prep and E-Commerce Solutions preps online-arbitrage and retail-arbitrage inventory in Pennsylvania, where clothing and most grocery items are sales tax free. No city is published. Base prep is $1.75 a unit below 1,000 units a month and $1.50 above it, with multipacks and specialty categories priced separately: $3 for shoes including size inspection and sticker removal, $5 for glassware, boxed collectibles or reboxed shoes. Merchant-fulfilled orders are $4. There is a 400 unit per month minimum, and clients must run Inventory Lab, since shipments are built from it. The operator offers a non-compete on client products. Three cautions worth weighing. No phone number is published anywhere, so email is the only channel. The site has been unchanged since roughly mid-2024. And the same operator sells a $75 arbitrage lead list with, in their own words, no US-based vetting, and earns affiliate commissions from three competing lead services, so a prep client sources in the same market their prep center sells into.

FastFBA3PL runs a warehouse at 474 Pike Road in Huntingdon Valley, Pennsylvania, in the Greater Philadelphia area, and pitches fast turns into Amazon fulfillment centers across Pennsylvania, New Jersey and New York. Prep pricing is tiered by monthly volume and published in full. FNSKU labeling is $1.10 per SKU at 50 to 2,000 units a month, $0.80 at 2,001 to 7,000, and $0.60 above that or on a private label shipment of 100 or more per ASIN. Bubble wrap adds $0.50, oversize above 20 lb or 18 inches is $1.80, and removal order relabeling is $0.90. Sets and bundles run $1.20 to $1.90. Beyond prep they price FBM order fulfillment from $2.00, pallet storage at $30 to $40 a month, container unloading from $450, pallet formation for FBA at $25, and product photography. The site names four team members including the chief executive. One caution. The About page dates the founders' Amazon business to 2016 and the first warehouse to 2017, but the Pennsylvania company behind the brand, Vinzoo LLC, was only formed in November 2020 and the domain registered in January 2021, so treat the longer tenure as the operator's own account.

Dispatch Fulfillment is a 3PL in Vandergrift, Pennsylvania, running FBA prep alongside FBM and direct-to-consumer fulfillment, Walmart Marketplace fulfillment, warehousing and freight out of a stated 20,000 sq ft facility with 4 loading docks. The Amazon line is a real inbound prep workflow, not a relabeled pick-and-pack page: they scan inventory in, inspect for damage and count accuracy, poly bag, bubble wrap, apply UPC or FNSKU labels, bundle or kit, build the FBA shipment plan, and ship to the fulfillment center. Pricing is published per unit rather than quoted, starting at $0.75 for FNSKU-only and $0.95 with polybag and suffocation warning, with no monthly minimum. Two cautions. The company's own About page gives two different founding dates, 2017 in one paragraph and 2015 in its timeline, while the Pennsylvania record for Dispatch Fulfillment LLC shows 2023 and the domain dates to 2024. And no phone number is published anywhere on the site; email is the only direct channel.
