Here's another Walgreens $5 off $20 coupon good today and tomorrow only. Please note the wording on the coupon: "Purchase amount of $20 or more must be before taxes and after all manufacturer and Walgreens coupons and discounts." Just because the coupon goes through before coupons doesn't make it right to use it that way when it specifically states not to. Now, with that said, there is still money to be made with this coupon. Bargain Briana shares a scenario here, and Deal Seeking Mom shares one here.
