Do you find that sales tax is a factor in making purchases?
Personally, if I can find an item locally for approximately the same price as an online retailer, I will buy locally because of the instant gratification aspect, as well as the ease of return and not having to deal with the hassle of having an item shipped.
I'm not sure how I feel about this, but they make good points. If the tax is already due, and people are simply ignoring it, providing tools to enable states to identify and collect revenue they are due makes sense. On the other hand, I think sales tax is stifling when combined with income tax. I'd much rather see no State income tax, and higher sales tax rates, so that the government is limited in it's spending based on the growth and economy.
