Just out of curiosity, and thinking of a brick-and-mortar store regardless what state you are in, what if the customer is paying cash and doesn't want to tell you where they live?
I remember a long time ago, Radio Shack always wanted your name and address for a sale no matter what you bought, even batteries. I always told them no and that it was really none of their business.
And so you know, I am not anti-tax, just anti-stupid-tax :)
