Pringles--Illegitimate Offer?

A couple of days ago I posted about a FREE coupon for Pringles Xtreme found on Facebook. As I was searching for coupons, I came across this offer several different times from several different blogs. It turns out that this offer was not mentioned on the Facebook Pringles Homepage, so it seems like it might not be a legitimate offer...not sure if it is or not.
If you signed up for this offer, you might want to go ahead and remove Pringles Extreme from your Facebook account.

Here’s what you'll need to do:
- Log into your Facebook Account
- Click on Account (top right corner)
- Click on Application Settings
* Scroll down the list and find “Pringles Extreme”; click on the “x” to permanently remove it from the application page; be sure to hit the “remove” button and the “okay” button. Pringles Extreme will no longer have access to your data and will be removed from your profile and bookmark.

Sorry about any confusion!

Thanks Hip 2 Save and Shelli!
