I not sure the sellers are the ones that are the clowns. My guess is that they end up getting their money enough times that they turn a nifty profit. Yes, their are a lot of people who try to make money buying and selling items on ebay.

In your example I am sure that even though some clubs go for 350, that you have buyers who walk into the local golf shop and see the same irons for 750, that 550 seems like a real bargain, without spending a lot of time on the computer to find the best bargain.

Ebay just has to hurt the big golf outlets.
