News today that Target, WalMart, and other major online retailers are starting to charge salestax on their online sales. Up until now, internet sales have been exempt from sales tax, but now, the big boys are starting to charge it. Their stated aim is to make sales tax a standard on the Net. For a long time, bricks and mortar have complained that clicks and mortar have an advantage by not charging tax. (Of course, they don't mention shipping.) In fact, the large companies are just tying to raise the bar for their smaller competition. The larger companies involved all have a significant retail presence in many states.
