Edit/Update (8:45AM PST): The deal is dead. But if you got it, word is that Gamestop will email you later with an additional code for the Season Pass since that is what we were "supposed to get". So not only do you get the full game for $20.00, they are also supposedly honoring the sale of the Season Pass. $80.00 worth of products for $20.00! This information was acquired based on a few experiences some people had with customer service this morning.
Edit/Update #2 (12:15PM PST): I just contacted Gamestop support via online chat, explained that I got the "wrong code" (/wink), and this is the message they sent me:
"At this precise moment we have been confirmed that this issue that you experienced with your game is a known bug or error as there has been a lot of orders for the same item that are experiencing the same problem. The tech department is working diligently to have this situation solved as soon as possible, What happened is that the manufacturer of the game had an error and unfortunately it ended mixing up the season pass and the normal game; Our main department is currently working on the issue and we have been instructed to take your email so we can send you an email with the resolution, please take in consideration that we do not have an ETA for this but we will do our best to solve this problem ASAP. We deeply apologize for any inconvenience this may cause. We appreciate your patience on the matter."
