> I sold digital goods on eBay a few times (like, less than 10 times) and I've already got 3 (!) people claiming their purchase is "unauthorized" after I sent them the goods (redeem codes, so I can't really let them "return").

This shit is why I don't sell on eBay anymore.

I have a friend who sells stuff on eBay a lot (or at least, used to), and he says about 5% of his sales go to scammers who will request refunds claiming they never received an item.

Of course, now that I think more on it, I wonder how many of those 5% were scammers versus how many of them simply had their package stolen from their front door.
