I haven't seen any specials on it. I pre-ordered mine through Amazon. And they gave me a credit as well since I guess when it came out last week, it was cheaper than I'd paid them.
I liked that feature enough that I'm going to pre-order a few more movies from Amazon that I want to get. LOL
I ended up just going by Target to buy it last night. The regular DVD, not Blu Ray or anything, was listed for $19.99, but when it rang up it gave me a $3 discount!
Edited: went by Target, NOT Costco. Got caught up reading Pesky's post!
