Looks like I'm not needed here.
Yeah, Walmart won't price match B1G1 deals usually. Now, sometimes Toys R Us does something like Buy One, Get One 40% off, then they show a bunch of games and put the regular price on them. Walmart *should* price match that, since the sale price of the games can be determined by looking at the ad. However, even I've had issues getting this to happen.
As for the Gift Card - officially, no, they won't price match that. However, if you get a nice manager, they might make an exception.
