Also, If you bring in over 10,000$ via paypal in a year you really really should report it on your taxes. If you sell less than 10,000 than its probably not worth reporting, but once you hit the 10,000$ mark the government will take notice. The IRS does look at payments received though paypal, even more now than years before.
