Did you know that Commissaries will take Walgreen's register rewards as long as the verbiage is correct!?
If your register reward states "Redeem at" or "Redeemable at" you can use it at your Commissary, however, if your RR states "only" in the above phrases you can not use them.
They will be used as a manufacturer coupon and will deduct the rewards amount from your total owed! How awesome is that?!
Go here to print off a copy from DeCa's Facebook page clearing this up for all of us Commissary couponers!
