Oregon Prep Center

Conor Chang founded Oregon Prep Center in Portland in 2023 and still runs the warehouse himself, so the person prepping your inventory is also the person you talk to. The Oregon address matters for arbitrage sellers: it sits in a sales-tax-free state, which keeps sourcing costs cleaner. Pricing is a la carte and tiered by volume, starting at $1.70 per standard unit for low-volume sellers and dropping toward $1.05 at 2,000-plus units a month, with wholesale rates quoted as low as $0.40. There is no monthly minimum, and a $250 registration deposit is credited back once you ship 300 units in your first three months. Every order includes seven days of free storage, and the warehouse runs seven days a week. It handles hazmat and oversized items and holds a 4.5 Google rating across 14 reviews.
