Use it and the 10 off Sorcerer's Apprentice, buy combo packs for Beauty/Beast, Toy Story 1-3, Christmas Carol, Monsters Inc, Cars, or some other junk and after you get 5 combo packs get a blu-ray for 60 bucks!
Amazon does seem to have an unpublicized $10 off promotion if you buy the 3 disc Sorcerer Blu-ray with the 4 disc Fantasia Blu-ray (which I believe matches a Target and BestBuy offer.) Put them both in your cart and just before you get to the final checkout the $10 discount shows up. At least it did with my order. Not sure why this promotion is not listed with the products.
