This week it's been reported that there is an unadvertised deal on Frito Lay chips at CVS. The small bags that are priced 3/$1 are generating a $1 EB on 3 and the limit is 5. So here is a deal you could do to score some free chips:
Buy (15) Bags of Frito Lay Chips= $5 and get back $5 in EBs!
Please be advised that this is an unadvertised deal so if it doesn't work at your CVS there's no way to report it to the cashier for correction since it is not something that is marked on the shelf or in the ad!
