Let's promote tax evasion, right?
I hope you truly understand what "Tax Evasion" is? It's perfectly legal for people to buy products and not pay tax to the store they are buying it from, provided the store doesn't charge tax based on the state the customer lives in. That's not tax evasion. When doing your taxes you have to claim those products on your tax form. If you choose not to then at that point you're cheating on your taxes......but if you think most people aren't creative on their tax forms anyway then you're sadly mistaken.
