I gave it a shot but the double stack at TRU didn't work. Tried Just Dance and Just Dance 2 and only 1 game came up 50%. Also, if you try to stack one of the eligible Wii games with Mario Sports Mix, you'll get 50% off Mario Sports Mix but the gift card promo is eliminated (although I still got a free Mario shirt). Looks like the TRU glitches are pretty much getting closed up now.
