CVS Unadvertised deal on Frito Lay products!!

Many reports are that CVS has a unadvertised deal going on buy 3 Frito Lay chips for $1 get $1 ECB, my store did not sell these bags. They had small bags but not the 3 for $1 ones. 

I did get the Frito Lay Sunflower seeds and Frito Lay Peanut single size bags which are $0.50 cents so buy 3 get $1 ECB back! Their is a limit of 5 so you can buy 15 and get $5 in ECB's back!

Here's my deal I did:
Bought 14 peanuts and 1 sunflower seeds Total was $7.50
I used $5 in ECB's I already had
Payed $2.50 out of pocket
Got back $5 in ECB's!
