Prep Center Los Angeles
Commerce, CA
California has the highest statewide base sales tax in the country, 7.25%, with local taxes on top. Wholesale sellers buy tax-free with a California resale certificate, but online arbitrage buys shipped here are usually taxed. California's strength is imports: the ports of Los Angeles and Long Beach together form the busiest container port complex in the United States, which makes the state a natural first stop for private label goods coming from Asia. The Inland Empire, east of Los Angeles, is one of the largest warehouse regions in the country. Labor and space cost more here, which often shows up in per-unit prices.

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.
