Even though I submitted my gift card number and PIN, the full amount was charged to my credit card in error. It may be the case the content of the fields in which I entered the gift card number and PIN were omitted without my knowledge. However, if so, then the design of the online ordering user interface is inadequate. UPDATE 12/9: My credit card was immediately refunded when I picked up my purchase, and once that was done, I used the gift card as intended.
