What can Apple Support do? They don't have anything to do w/ my financial institution.
Can somebody answer for me, if I do purchase $900 in gift cards for my iPad, what would happen if I needed to return it? Could I get my credit back or would it be Gift Card only?
call apple support. my parents had a similar issue when they were trying to make a large purchase. apple does not charge you until the item is shipped. but they do a micro hold transaction to verify the card. like $1 or less just to process the order. my parent's card was rejected because it wouldn't take this transaction as it assumed fraud, etc. ask apple to bypass that step and you should be fine. at least this is everything i was told at the time.
oh, and calm down. its a machine, and you want to be able to buy it now so you can pay more for it in the long run? not the end of the world.
