I bought a license for an app recently and didn't get my license key because I entered gmail.con or something. I was really pissed at them for about a day until I pestered them and they sorted it out. After it was over I was still kind of annoyed with them, really for no good reason, even though I was the one who goofed up.

Hey, maybe that was me! I sell software online via PayPal IPN, and at least once a day (often more) I get email from customers angry at me for not sending their license key. Invariably it's because they no longer use the email address that PayPal thinks they do.

I tried highlighting this in the FAQ and on the purchase page, but the rate at which it happens didn't seem to change.

A good solution for them would be doing an email confirmation before charging someone's card.

Well, in this case they use Paypal for payments, and I used my Paypal account, so I got the receipt just fine, but never got the license key. So the possibility of "I gave them the wrong email address" never entered my mind for me to double-check.
