There's plenty of stooges buying from key reseller sites who very pointedly have to wait 24 hours to get a game key. Maybe they think it's the normal mode of operation.

All of mine showed up while I slept last night. Now to pick one to play tonight.

Sadly the Game I claimed from the Ninja Giveaway never got added to my account, I waited several days, and I contacted customer support to resolve this issue and they couldn't help with adding up the game by themselves because by the time they answered my request the code that I had obtained had already expired and they couldn't do anything about it, so I recommend people to claim their codes at least a day before expiration date, because customer support can take a day to answer back.
