My Saturday cleared up and I can most likely stop by the store. I'd be happy to pick one up for you if they're still available!
ETA: I checked the DSF post on Facebook again and someone said it's on shopDisney. I checked and it's still there. This may be the better option for you (I would guess it's about the same price in store or online) and you'll get it quicker.
