Prep centers in Michigan
Michigan charges a flat 6% sales tax, and cities and counties cannot add their own, so the rate is the same everywhere. Wholesale sellers avoid it with a resale certificate, while online arbitrage buys shipped here are usually taxed. Detroit is the busiest trade crossing between the United States and Canada, which makes Michigan prep centers useful for Canadian sellers who sell on Amazon.com and for U.S. sellers who also ship to Amazon.ca. Detroit and Grand Rapids are the main distribution hubs, and from there a truck reaches most of the Midwest in a day. Space and labor usually cost less here than on the coasts.

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.
