Just this year one of my apps has found some popularity among european users. I thought that was good until I started getting chargebacks. about 20% of the sales i got from europe have ended in a chargeback and i not only lose the $20 for the s/w sale, but I'm also charged $20 for each chargeback. So i'm basically losing 40% of my profit due to chargebacks. I was originally using Digital River (Share-IT) since i could provide immediate download/registration, but tried switching that app to PayPal and doing it manually. Still getting chargebacks, though. Hard to believe someone can claim they didn't authorize a purchase when the sale came via their email address and the download/registration was only sent to that address. I even attachedd a copy of the email to them with their registration to the PayPal Resolution Center. I'm switching that app to the MAS now to see if they're any better. I know Kagi went out of business due to chargeback fees and i'm not nearly as big as they were. Anyone have any experience dealing with chargebacks positively? very frustrating.
