A side note, some years ago when Christine Whitman was Governor of New Jersey the state was desperately searching for revenue. They began poring over hobbyist trade shows for out of state vendors selling sci-fi models, dolls, etc. If they found someone who had been to the state a few times they would seize their goods, estimate the sales tax owed and require it to be payed for the release of the merchandise. Imagine holding some action figures for payment of $200, what cruelty. The most hilarious part of the article was the closing of the article when the tax department said they were going to begin looking into bars and restaurants because they may be concealing income. Of course this never happened as the bar owners aren't powerless (and they are concealing huge income,mostly cash business you know).
Ebay sales are not tax free. If you are selling items as part of a business you are required to show it as income. It is therefore, part of the official report on the economy, not some secret asset.

Oh, and by the way, if you don't know the economy is in bad shape, even after massive tax cuts, you aren't looking.
