I also had a lot of headache when a seller charged me twice and tried to send me another product because I had to charge back several transactions while explaining "yes, the FIRST one was legitimate and I got he product, but the later ones are not". I had to charge back twice because the seller kept on charging me on the same credit card number! At least with Bitcoin you're only in for whatever you pay.
