I just received my tax refund and want to use a portion of it to purchase my AP. However, I have 3 gift cards (2 AMEX and 1 Visa) that I want to use towards the cost. Can I use 4 types of payment for the transaction? I'd use the 3 GC's first and then my credit card to pay the balance. If this can be done, can it be done over the phone with MS, or does it have to be done at a Guest Services desk/booth in WDW?
