If you also want "Bambi", there's a $3 coupon for it in the Incredibles box. Use your new $5 gift card with the coupon, and you basically end up with both videos for about $20.
Disney's also got a long-standing deal going where you can get a "B-list" DVD (Robin Hood, The Rescuers) if you send in three proofs of purchase, so if you can find another cheap Disney movie (not necessarily at UE), you could end up with four DVD's for about $30-$35.
The only problem is that you've gotta put up with Ultimate Electronics, which has been an annoying experience for me both of the times I've ever entered the place. Unlike Best Buy, I always seem to be the only person there, and I'm always followed by a salesman who wants to give me bottled water and sell me a plasma TV when all I want is a friggin $12 DVD.
