I have heard of people making money from putting art on CafePress and then selling them on Ebay. All you have to be careful of is getting the money from the auction on Ebay 1st then shipping it directly from CafePress to the buyer. I guess it does take some accounting to keep track of the orders from Ebay and the shipments from CafePress since there is some processing time from both places that you have to juggle. But it can be done if you want to pu the effort into it.

They have several threads about people who have done it in the CafePress forums if you want to check it out.
