Transferred Prescription WARNING

I usually get my prescriptions at Costco, but we were heading out of town and I couldn't wait for Costco to open, so I went to Walmart. Walmart charged me $4.00 for my prescription, which I was really excited about. I have refills on for this prescription and decided to take it to CVS when I needed a refil, since I had a coupon for a $25 dollar store card with a new or transferred prescription. Before I dropped it off I asked how much the prescription would be there. I was thinking that they would be a little more than Walmart, but I would still probably save money because of the $25 store card. The lady told me the prescription would be $64!!! I was blown away. I couldn't believe that they would charge $60 more than Walmart! Needless to say, I didn't purchase my prescription there, and I seriously doubt that I would ever take a prescription there again.
