How do I get a receipt for iTunes purchases. I know I used to get them for purchasing apps, but I can't figure out how to get email notification of my iTunes purchases.
Receipts should be automatically mailed to you. There's nothing you need to do (or can do) other than confirm that your current email address is correct in your iTunes Store account and make sure no anti-spam filter is blocking emails from Apple. It sometimes can take a couple of days for a receipt to be sent.
You can always look up purchases by logging into your iTunes Store account and going to the Purchase History.
EDIT:
Is there any way to speed up how quickly I getthr receipt though?
