I know on Apple's site the BTS $100 credit says you can use it on all 4 stores (Mac App, App, iTunes and iBookstore). But is the credit linked to your Apple ID or the store you redeem it on?
As in, if I redeem it on the Mac App store, and still have some balance left over, can I use the rest in another store?
