Just wondering if anyone is doing this as well? Apparently you can use the codes twice.
Some people might want to possibly swap codes with each other to double their codes. I currently have 3 Dew codes (20oz) & 2 Doritos codes (3oz bags - 1 Nacho & 1 Cool Ranch). I grab my bags of chips from the back to try and minimize the possibility of people jacking the code and the dew codes are underneath the caps so no worries there.
When Halo 4 was about to come out I took a picture of the code on like 250 bags from grocery stores, you were only allowed to have 200 games of double Xp though lol.
