The only bit that would be up for taxing would be any profit made from that sale. Buy for 2 dollars sell for 3. Only the 1 dollar profit is in play for taxes.
Even then it can be exempt or removed by other items in the tax code. That profit is not part of the sales tax system. It is part of the income tax system.
