It looks like the Kelloggs Register Rewards going on at Walgreens this week is rolling. This means that you can use the Register Rewards from your first transaction to pay for the next and you will get another Register Rewards. Combine this with coupons to get the following deal on Poptarts:
First Transaction
Buy two Pop Tarts 8 pk. 2/$5
Use $1/2 Pop Tarts printable
Pay $4 and get back a $2 Register Rewards
Second Transaction
Buy two Pop Tarts 8 pk. 2/$5
+ Buy a small filler item
Use $1/2 Pop Tarts printable
Use $2 Register Rewards from previous transaction
Pay $2 and get back a $2 Register Rewards
Rolling Register Rewards is not the norm at Walgreens and this may in fact stop happening on this offer at any time. If you are interested in this deal try sopping sooner rather than later.
Thanks Discount Queens!
