I called Frito lay for a donation for a fundraiser. I need to purchase 3 boxes of 50 single serve chips at a cost of $15.99 a box. I spoke to customer service and they said they would send me coupons. I wasn't impressed but it's better than nothing . Today I received my coupons and was discussed to see $1.00 coupons and .55 cent coupons. I can only use 1 per transaction. Shame on Frito lay for nothing. I AM MORE THAN PISSED OFF I User's recommendation: Think Twice before supporting Frito Lay. They certainly do not support us.
