Walgreens has Back-to-School fliers available up at the front of the store (by the weekly ads) which contain a coupon good for $2 off Huggies wipes. Since this is a store coupon, you can also combine this with a manufacturer's coupon to score a great deal on wipes.
Huggies (72 ct) Wipes $2.79
Use the $1.50 coupon from Coupons.com
Plus, use the $2 Walgreens Back-2-School coupon
Final cost FREE + possible overage!
Make sure you hand the MQ first then, the store coupon. If you don't the coupon will beep and they won't allow it. Trust me on this!
