DD used several to make a purchase on our first cruise in December...she had several that she hadn't spent in Disney World and couldn't find the "thing" that she just had to have so she saved for the cruise. She has wanted a Kate Spade purse for about a year, but this momma is cheap and doesn't understand spending $200 on a purse. So she sees a bag she has to have. I tell her to ask if they will take gift cards and if not I will "buy her gift cards" if that is what she really wants. Long story short my girl is now the proud owner of a Kate Spade bag bought with Disney Gift Cards.
The clerk, did have to take the cards and scan them in the main store, so perhaps that might be where some confusion came in on the other thread.
