Whereas a vendor who has received wired funds has to do... absolutely nothing in order to defraud the buyer. Just don't send the item. Hell, you don't even need to have the item in the first place.

I'm just trying to point out it can work both ways.

And we're talking as if this problem was rampant. It's really not. From personal experience of over 650 transactions bought and sold in 9 years, the only one I have had a problem with was one where I paid by bank transfer. I just wrote the funds off in the end, was just too difficult to get them back. Anecdotally from other forum members it seems not to be a problem. eBay's profits are down of late, yes, but there is still an astounding number of transactions going through. Would that be the case if there was an epidemic of charge backs from credit cards? I doubt it.

In the end, it's each to their own and use whatever payment method provides you an acceptable risk. I'm happy with PayPal. Your mileage may vary.
