Unfortunately, the sources provided do not mention any information about a Lipitor loyalty program. Lipitor is a prescription medication used to lower cholesterol levels, and according to Drug Patent Watch [1], it is no longer under patent protection and is available as a generic medication. Therefore, it is unlikely that a loyalty program exists for Lipitor.

The other sources provided, Krispy Kreme Rewards [2] and myWalgreens [3], are loyalty programs for Krispy Kreme donuts and Walgreens pharmacy, respectively. Krispy Kreme Rewards offers points for every purchase that can be redeemed for free donuts, while myWalgreens offers personalized deals and discounts on Walgreens products.

In summary, there is no information available about a Lipitor loyalty program. However, if you are interested in loyalty programs, you may want to consider looking into other options such as Krispy Kreme Rewards or myWalgreens.
