I owned a retail music business with an online presence for over 30 years. In the musical instrument market, between 25-30% of all online credit card transactions are either fraudulent or returned. That is HUGE, and winds up costing vendors millions. Think about it--what do you do with a returned item? It is no longer new, and no one is going to pay the same price for an open box item, but as a vendor you are at the mercy of the credit card companies. Regardless of approvals received, if a credit card holder decides to protest a charge, for whatever reason (bogus or not), the vendor is at the mercy of the card company. You are charged back the amount and required to provide proof of the transaction. These decisions invariably go to the cardholder. (International sales are even worse in terms of percentage of loss.)
This all caused me to turn off all of the automatic credit card acceptance on my website after getting stung for thousands of dollars despite getting approvals. I just required a purchaser to call me on the phone so I could discuss the transaction one on one, do the research, explain my return policies, and make my own decision about accepting a sale. I still sell on Ebay and I've been an Ebay vendor since 1998 with a lot of success. Paypal is much safer, but you are still at the mercy of the cardholder's whims, and are required to issue a refund for any reason that a cardholder desires.
Through Paypal fraud is at a minimum, but refunds are still an issue, but not nearly the percentage of a problem that they were on my website. I also do no international transactions, finding far too much fraud involved in international sales. So, sorry my international friends, but your "brothers" screwed the pooch for you on that one.
Just think about it the next time you
buy something online--that vendor has to make up for all of the fraud and losses due to returns somehow, or he's going to go broke quickly. Credit card fraud is a huge factor and costs everyone billions of dollars. So sad.
The bright side is for the purchaser. Never use a debit card onlline. But remember with any credit card purchase you can always protest a charge, protecting you from a fraudulent vendor. It just doesn't work very well in the opposite direction.
