Starting 3/16 until 3/29 Walgreens is having their Happy Cash Promotion. Basically when you shop between those dates and spend $30.00 you will earn $5.00 in happy cash. If you spend $50.00 you will earn back $10.00 in Happy cash. Happy Cash is similar to a register reward, but cannot be redeemed until the following week (3/23-3/29). You can only earn one happy cash coupon per transaction. Also, Happy Cash is earned AFTER in store coupons and BEFORE manufacture coupons. Meaning, you have to spend $30.00 after any store coupons are scanned in order to earn the promotional coupon. With everything, there are exclusions so please read the entire promotional disclaimer before shopping!
