On a whim, I decided to pull into a Gamestop on my way home to see if this B2G1 and trade in GTAV would work and it totally did. I snagged a Ps3 and 360 copy of GTAV and then they had a complete Limited Edition of Kingdom Hearts 1.5 that they just received in today for my third game.
After checking out, I explained to the employee that I wanted to sell the GTAV's back to them for 48.00 each with the promos. He thought about it and after doing the math, he said, "That's BRILLIANT! Totally brilliant!!" I bought an $0.89 copy of Guitar Hero DS to trigger the promo and walked out of the same store with the $3 LE KH 1.5, $1 GH DS, and $95 of credit (that I already planned on using during Black Friday anyways).
Great deal!! Thanks a ton to whoever originally put that together!
