CVS Pharmacy Care Rewards Program

I have been to several CVS Pharmacies and all have had the same problem. Every time they ring in a product that is on sale that product rings up (at least for me)at the regular price they(CVS)have had to adjust it several times going back several times to check and see if the product was in fact on sale (Which it was)Having to adjust it every time so I emailed CVS and they told me they talked with that manager of CVS about the problem. But again hearing not listening the email stated that it was several CVS's not just one and it took them several days to email me back in a response to my problem which is now theirs because I know longer do business with CVS.
