Target has a Pharmacy Rewards program. For every 5 prescriptions you fill, you are mailed a 5% off all of your purchases card for the entire day you choose to use it within in its expiration. I am a member of this and have received these many times. It’s a nice little perk. You can enroll for the program here, or if you are already a member you can use that same link to create an account online to keep track. You can also see how many prescriptions you have filled towards receiving your 5%off card by checking the bottom of your receipt after picking up your prescriptions.
Target also has another Loyalty Pogram for their RedCard holders which also offers the perk of 5% off your purchases. To find out more check here.
