Found a $20 Blizzard Balance Card in a 12 Pack of Sierra Nevada Inside the 12 pack of beer, I found a Blizzard Balance Card worth $20... The last place I'd think to find something like this... but after putting the code in, I get an error, and the $20 isn't added. I'd like to know why there was a game card in a SEALED case of beer, and why it won't work, even though I personally scratched off the code and it confirmed that it worth $20 on the Blizzard site.
