So i bought four bags of doritos, and the codes were used on them all…
Does anybody know a way to get some working codes?

Well no need to buy the doritos if the codes are right in back of the bag. Stupid idea.

I don’t understand why they didn’t put the codes on the inside…

Because instead of someone griping about a used code someone would have choked on it.

Because Doritos is a fail lol. Shouldnt have been on the back. dumb idea.
