I've heard it. They didn't push too hard.
I pre-ordered the Persona 3DS and game for my wife. I like it when she tells me exactly what she wants for Christmas.
I'm sure it's different for each store. My bf wasn't told to push it heavily - just passively mention it to folks because it's so new.
It doesn't sound any different from something like a Target CC or anything else (only useable at their store and not as a regular credit card elsewhere), and the interest rate is awful, but it's not necessarily a bad thing to get for someone who has no credit or bad credit. They gotta start somewhere if they wanna start creating a good CC history.
I actually would've considered getting it (because I buy so much from Gamestop), but at the moment, there are no perks to using it - no extra Powerup points, discounts, or anything. Hopefully they'll have promotions associated with the card in the future that might make it worth it.
