While Amazon and Best Buy have the standard blu-ray/dvd/UV version of Dark Knight Rises for $18.99, looks like WalMart and WalMart.com decided to beat them by a buck.
Just picked up a copy at my local store for that price (since Amazon and BB charge tax in Texas, WalMart has the best price online and instore). Glad to not have to
wait for delivery and get a little savings too.
Here is the link for the online version (free shipping).
