I can teach my dog to fetch, but I cannot explain this to you. How many ways can I say that there is no double STATE tax. When the vendor purchases from the manufacturer he is not taxed by the state.
The vendor has to PURCHASE state tax stamps from the Dept.Of Revenue..before he can sell them to a retailer. The manufacturer doesn't do the tax stamps. Individual states distribute the stamps. Taxes vary. Whatever the vendor buys and doesn't sell, he eats the state taxes. He already paid them. If someone buys a carton in any state, they have paid that states taxes. The tax stamp proves it.To have another state try to make you pay their taxes as well, is called double taxation.
I give up, my dog is smarter than you.
