I have been out of the coupon loop so I have not seen this coupon but I guess it is out there on the Internet and is fraudulent so if you have printed it - please throw it out!

Here is the statement from Frito Lay:

The $5 Doritos coupon that is being spread throughout the Internet is counterfeit. It was not created, authorized or distributed by Frito-Lay. We are taking steps to notify our retail customers about the fraudulent coupon and to identify its source. You should not knowingly use a counterfeit coupon. We sincerely apologize for the disappointment and confusion this has caused. Please watch for valid coupons and sales in stores, magazines, Sunday newspaper ads, and on our official websites.
