In states where Amazon has some type of presence, the sales tax alone has already made buying some items (particularly items which are essentially priced the same as local retailers) not worth the hassle of waiting for shipping and whatnot because it essentially comes out to being the same price locally, and if you buy it local you can walk away with the item in hand vs waiting 2 days. Mind you I still use Amazon to buy a lot of things, but I have definitely become much more selective recently.
Amazon already has a presence here in VA, but I still buy from them, because they carry things that I cant get at my local stores. And usually but not always they are cheaper even with the added tax..And if the item is stocked locally, shipping is 1 day...
