This pesky thing called work keeps getting in the way of checking this thread more frequently.
I've been successful twice in buying Disney gift cards online at
Best Buy with in store pickup. Had two other orders cancelled though. I haven't tried to buy Disney in store yet but I've purchased eBay in store twice now without a problem.
If for some reason I get denied, I'll try one of the other two Best Buy stores in my area.
Worst case I try online ordering again. After two orders cancelled I added a small non gift card item to my order and it went through without a problem. Not sure if it was a coincidence though. Was nice to get Ebates on the entire order even though they say they exclude gift cards.
