Look for the Infant Care Book and WBrand Savings Book at Walgreens to pick up cheap diapers this week!
Walgreens Brand Diapers, 2/$10
$2/1 Walgreens Coupon from Infant Care Book
$1/1 Walgreens Coupon from WBrand Savings Book
$2 ea. after stacked coupons!
You'll just need one copy of each coupon because the Walgreens coupons are automatically deducted based on the number of products you have, so the first will deduct $4 and the second will deduct an additional $2.
Update: You may actually need two of the $1/1 coupons as they are technically manufacturer's coupons. I'd recommend being prepared with two just in case.
