TheMonkofDestiny: Hadn't seen any post to suggest that myself (and I've been keeping up with this and the announcement thread and occasionally peeking in on other related threads roughly all day). Unfortunate for those unlike myself (since 1 is all I'm willing to concede in my monthly budget toward) if true, however.
Think it was in the blue thread, but its also possible the only games they didn't have yet were out of stock and their speculation that the cause was they clicked it as a gift was mistaken.
There have been a couple times today where people have claimed to get a game they already owned while not owning many other games in the promo. Hard to say if it was a momentary glitch or something else.
