I just saw this... I haven't see Walgreens do this before. It's not a coupon. You get a $5 register reward when you spend $25. This deal ends Saturday December 6th.
Register rewards expire in 2 weeks, not one month like ECBs, so be sure and spend them before they expire!
Speaking of register rewards, they changed the wording on register rewards again so you can only use one per transaction. So if you have more than one register reward to spend, break up your order into however many transactions you need to be able to use them. If you happen to get a survey at the end of your receipt go online and fill it out and be sure to mention how inconvenient that is for both you, the customer, and the cashier.
