This just means more sales from websites other than amazon.
Barnes and Nobel and Underarmour collects taxes on their sites. I believe all of the department stores do as well.
Are people really choosing online stores based on which ones help them cheat on their taxes?
I don’t think so.
Of course, I think publicly declaring that you are going to change who you buy from so you can cheat on your taxes is probably not a smart thing.
Most states offer a 10% or more finders fee to people who turn in tax cheats. Imagine an enterprising person who came through FreeRepublic and collected the names of all the self-confessed non-use-tax payers.
NOTE: I do not think people should do that. I hate the idea of a nation of bounty hunters. I think people should do what is right because it is what is right, not because they are afraid of being caught.
