This type of action doesn't surprise me. You are to report internet purchases of certain value to your state for proper taxing. Look at what Minnesota did. I've said for years that they will start taxing the Internet sales at some point and yeah, I can see it happening.
Logistically it wouldn't be that hard to do. It would be called something like a National Internet Sale's Tax. WHAM!!! Done and over with. Then the Fed Government would take a piece of the pie and then divide it between the 50 states. Not as hard as one would think. But its one more reason why I wouldn't order even less on the internet. The stuff I want, is imported in from Russia so it would make it nearly impossible to attain some of that stuff at a reasonable price. Since I can't walk in stores to buy it and thus, I have to order it online or just not have it. And with this being America, I should be able to get it online at minimal hassle. As the shipping costs of what I order isn't exactly cheap.
