We have a dog on two "human medicine" prescriptions. I have been getting them filled at CVS and just recently realized I have been overpaying...by a LOT. I had no idea Walmart would fill pet prescriptions. When I compared prices, I saw I could save 90% on one of the prescriptions and 50% on the other! No drive-through, and it can be a pain to get prescriptions transferred, but if you are aggressively trying to find ways to cut costs while still giving your pets the best care possible like I am, Walmart is worth a look!
