On February 12, Walgreens will be having a "Friends and Family Day" with discounts of 15% on everything and 20% on Walgreens brand items. This discount can be combined with existing sales, coupons, and Register Rewards. You just need to show your "Friends and Family Day" coupon to the cashier before you're rung up.
There are two ways to get the discount coupon:
