Doritos are on sale for $2.00 each, when you buy at least two bags at Walgreens. My store did not have sale tags on the Doritos, but you can find the sale price advertised on page 2 of the Walgreens weekly ad. Find this ad near the front door at your Walgreens location. Buy two bags of Doritos to get the sale price and use one $1.00/2 printable coupon. Pay just $1.50 per bag!
