Double edge sword here folks. On line purchases are here to stay and may be considered the wave of the future. I hate to see brick and mortor suffering or closing down due to lack of business, but they do have to upgrade and move into the future. Maybe with an on line presence or maybe by trimming costs. Of course that helps kill jobs, thus the double edge sword.
Now we add sales tax to the mix and the multiple problems that go with it. Just in my state alone, there are state and county taxes that vary. Maybe only a fraction of a percentage point, but there still are many differences depending on which location you live in. Maybe a large corporation can come up with a program that addresses this problem, or maybe one will be sold in the near future.
Adding sales tax doesn't help a business' bottom line, it hurts it more than anything.
I question if the S.C. decision as being made more as an arm twist than a legal one, with their arm, the one that was v being twisted.
