What does that have to do with the validity of the central point, which is that states which gave Amazon a grace period during which it wouldn't have to collect sales tax[1] are now complaining that much more minor e-commerce shops aren't collecting sales tax[1]? Amazon's margins are thin and they're focusing on automation. Is it any more advantageous to have an Amazon warehouse in your state than it is to have smaller ecommerce outfits? [1] On inter-state sales, of course.
