If you haven't done your shopping at Walgreens yet this week now you can add and extra 15% off. I just got this coupon from Walgreens. A one day shopping coupon for Walgreens purchases made on on Friday. Use this coupon on Friday 2/12 to get an extra 15% off your purchases and 20% off Walgreens products. There are some restrictions, but it doesn't state that you can't use it with other coupons! Let me know what great deals you find.
