Editor summary

503 Prep is an FBA prep center in Salem, Oregon, run by 503PREP LLC, an Oregon company registered in February 2024; its site lists a warehouse suite at 298 Patterson St NW. Oregon has no sales tax. The core offer is per-unit FBA prep: receiving, visual inspection, labeling, packaging, bundling and shipping into Amazon, with free shipment creation. Rates are counted per ASIN per outbound shipment and step down from $2.00 a unit for 1 to 20 units to $0.70 for 501 to 1,000, with 1,000 or more quoted. Bundles of up to four units start at $3.00 a set and fall to $1.50 at 101 to 500 sets, plus $0.25 per extra unit; bubble wrap starts at $0.50, and items over 20 inches or 8 pounds cost double. It also processes FBM orders the same day at $2.50 an order plus $1.00 per extra item, forwards boxes and pallets, and charges $30 a pallet or $13 a shelf a month for goods stored more than 14 days in a calendar month. Cautions: the site says its first package shipped from Salem in October 2017, but the earliest records of the business are its domain and a federal carrier registration, both from March 2022. An October 14, 2026 state filing moved the company's principal address to 4925 Indian School Rd NE, Salem, while the site still lists Patterson St, so confirm the receiving address first. Contact runs through a Gmail address, a New York phone number, WhatsApp and Telegram. It publishes no FBA prep turnaround and no poly bag line.
