Drugs at different pharmacy chains: different prices?

I’ve found the best prices either at Kroger or Walmart depending on the drug.

You bet they do. Sometimes there is as much as a 50% differential depending upon the drug.

I have found Costco Pharmacy to be the cheapest by far, amazingly so. You don’t have to be a member to use the Pharmacy only. By law they must be available to the public.

You can also call several pharmacies to get a price quote and find the cheapest one.

Stay away from Rite Aid. Always the highest.

Pharmaceutical companies were not allowed until recently to advertise prescription drugs. (I think it was a good idea!)
Pharmacies are still not allowed to advertise the price of their prescription drugs, but you can call around and get their prices. Walmart has that great $4.00 program if your medicine qualifies. Costco also has some pretty good prices and you don’t have to be a member to use their pharmacy.

what @Buttonstc said: Costco pharmacy is the cheapest and you don’t have to be a member. a lot of people don’t know that. at the front entrance where you show your membership card, just tell them you’re going to the pharmacy. i think although i’m not sure you don’t have to be a member to use the optical either.

How do you change your Rx from one pharmacy to another?

@Jeruba ; Ask the new pharmacy to do it for you.
