The savings program at Walgreens is called Register Rewards. If you spend a certain amount of money, they will offer you RR’s. The RR’s are printed from a machine that is called a “catalina” machine; this is merely because Catalina is the company that makes the machines. Occasionally, the catalina machine will also grace you with extra coupons for other products as well! Anyway, for example, spend $10 and receive $2 in RR’s.
The catch with RR’s is that, technically, they are manufacturer coupons that are only good at Walgreens. So to use RR’s, sometimes you need to have “filler items”. For example, if you about to purchase five items and you have a coupon for each of those items, but you want to use RR’s as well, you will need to purchase a filler item so you will be able to use the RR’s. This can be anything you wish, but generally the cheaper, the better. I usually will use a small piece of candy near the cash register for about $0.33.
On the up side, Walgreens does offer store coupons that you can stack with manufacturer coupons. You can generally find these in the display near the front of the store, near the pharmacy, or at the beauty counter.
As with CVS, the best way to use the RR program is to roll your RR’s into another RR offer. This minimizes your OOP expenses. RR’s are as good as cash as well, so treat them as such.
