As of Feb 10th 2009 the resale of any children's items will be prohibited. This includes clothing!!!!
"Any uncertified item intended for children under the age of 12 will be considered contraband after February 10, 2009. It will be illegal to sell or give these items away to charities, and the government will require their destruction or permanent disposal, resulting in millions of tons of unnecessary waste, and placing an enormous strain on our landfills."

I don't know about you but this sucks. I am a single mother and I resale my son's items after he is done with them so I can buy him new things he needs. I also sometimes buy used items for him.
