Now you can get cash back (and use our great savings coupons) on your Pet RX including heartworm meds, only at Petscriptions. We have no other merchants that can pay you for RX products for your pet except Petscriptions, so be sure to check them out before buying. And remember, your pet needs to be on heartworm meds all year round.
