I see. It looks like I got hit the $5 for the extra drummers and stuff without realising.
I wish Apple would not be so ambiguous and sneaky with the language they use.. phrases like 'Free', and 'Free Purchase" might not be free at all.
Then it adds all free downloaded apps to the 'Purchased' list,.. and always demands you to confirm your credit card details even to download any and all silly free apps. It's difficult to know what's free and and what moment Apple is deciding to take real cash from you.
I am certain it's this way by design.
I won't be using the Apple crook shop.. I mean store for anything again.
