GameStop always does that; it's one of the reasons I wasn't as able to get as many Saturn games as I'd have liked (well, that and the rarity and high prices of some of the games), as I bought the Saturn (and the Dreamcast, to some extent) late.
I thought the deadline for UMDs and GameCube games had already passed, though. I haven't been able to find any of them at the GameStops I visit for months.
