I paid $16.99 at Best Buy. I watched it with my wife (I saw it twice in the theater, but she hadn't seen it yet).
She was laughing so hard she cried on at least three occasions.
I am glad the article is wrong. I haven't gone out to the stores to check on the prices yet, but I bet it is something like 14.99 at the local Wal-Mart. That is reasonable.
