Prep centers in Washington
Washington charges a 6.5% state sales tax, and local taxes push the total above 10% in parts of the Seattle area. Wholesale sellers avoid it with a reseller permit, while online arbitrage buys shipped here are usually taxed. Washington is Amazon's home state, with many fulfillment centers south of Seattle, and the ports of Seattle and Tacoma bring in a large share of the goods imported from Asia, which suits private label sellers. Oregon, which has no sales tax, is a short drive away. Prep centers here also work well for sellers who ship to Amazon.ca, since the Canadian border is close.

A 0 to 100 score built only from facts we can check on a prep center's own website or in public records. It measures transparency and operations. It is not a customer rating, and nobody can pay to change it. Facts we could not confirm score zero, and every profile shows how much of its score rests on verified data.
