It comes down to location. Everybody would have a different experience. I can just go by experience with yard sales and what others have said. Your experience with GameStop is different from mine. I have several locations around my house and whenever I walk into any of the GameStop locations nobody is in the store other than 1 employee. Nobody looking around at all which can be surprising or expected. Yes you will find people giving certain games away. I know PS2 games have been in decline for years at least from my end.
