Consumer retail is evolving, as it has been forever, and will continue to do so into the future.
Local retail shops can cater to immediate gratification desires by shoppers. I can't just order up a latte on Amazon and have it NOW. If I need a new HDMI cable to watch a DVD with some friends tonight, then even free overnight shipping won't solve my needs.
But, for many other things... A new pair of shoes, a new coffee pot, a bottle opener, etc., I can wait 2 or 3 or 7 days to get the item. The Internet isn't going away, and even if I had to pay sales tax, I'd probably still continue to buy things on Amazon because it's easier for me than going to a retail store and dealing with potentially limited selection, crowds, etc.
These companies are simply NOT going to beat Amazon into submission. It's far too late for that, and I actively despise any retailers who try to increase my tax burden vs. offering a valuable service to me.
