Walgreens has Pepperidge Farm cookies on sale for $.99 this week. You can use the $.75 off coupon from the 5/6 SmartSource insert and pay just $.24!
The small packs are sometimes available for $.99 at CVS and Rite Aid too or Target will offer them in the Dollar Spot. So, a few other options to check if Walgreens is not convenient for you.
The coupon value is different by region but I got $.75 off in my paper.
