B2G1 Used - Gamestop

Does anyone know if the B2G1 used games coupon can be used in multiple stores in order to complete the three game requirement?

One GS has 2 of the three games and a different GS has the third.

I'd buy the 3rd game, take it to the second store, return it and then rebuy all three games with the coupon on the spot.

Just an idea.

Not gonna work. However, you may be able to get an employee at the second store to exchange for the game from the first one.

I have swapped a bad disc for one that worked at different stores like that.
