as a matter of fact, evetytime someone list an item on ebay, it's a contract. So you could bring the other guy in court.
But all the trouble that it could cause would probably cost you more than the deal you've made.
About 3 months ago, found a great bargain, there was an error in the listing should have been 200$ and not 20$ as i bought it, after writing a few time to the seller. He decided to sell it to me anyway, after a few weeks without receiving nothing in the mail, i wrote him back, he told me that item was probably lost in mail, and gave me a full refund....
So if you have a good deal, better pay for registered to be sure the seller really sent the item!!!
