“An odd annoyance has emerged among many App Store and iTunes users. Over the last several weeks, many Apple customers have reported that they are no longer receiving email receipts for purchases they made via the App Store or iTunes.”
I’ve been having the same problem. And this is a problem, because I need receipts for software that I purchase for my business. In fact, I had forgotten about this until seeing the article this morning, and went and got a bunch of receipts re-sent.
The biggest issue with this, however, is that without receipts I won’t see any unauthorized purchases, if, by chance, someone managed to compromise my account, or if I was billed for something I didn’t buy.
