Chevy & GMC Vans

is this legit ???
im going to print and try to use them lol.

Dunno BUT they were passing them out at "Skool" during a school cookout. They had a big bowl of Doritos on the picnic table. Then I get it in pdf format in an e-mail from a friend 50 miles away..... converted it into a format I could post.......

They work but I dont think they are leggit. Freind of mine works at Wal-Mart and used them to buy 15 bags and now there are questions as the supplier was never told of these coupons......
