i recently just upgraded to osx lion(july 30 here). Today I just received a receipt from itunes of my purchase with the receipt date as 01/08/11.
I have read about recurring charges from apple about this but not for credit card(i think the problem was paypal). I immediately double checked my account and sure enough there was only 1 purchase.
Im still paranoid though. I am in the philippines and I wouldn't want to call their US number(maybe only as a last resort). Was this just a matter of the receipt email being a week late? or is it a real double charge?
