Right now you can get a free 3 Roll Pack of Tums when you stack these coupons:

They will most likely adjust down one of the coupons so there is no overage. It is Target's corporate coupon policy to adjust down one coupon, but if you get any guff you may want to print Target's coupon policy and take it with you!
Thanks, Couponing for 4!
