Ann, you do not have to join it to use their Pharmacy. I am not a member because I would not go that far and I do not shop in bulk for just me. I go to the pharmacy for one medicine only. It is my sleep aid. If I get it through another pharmacy I have to pay about $200.00 for 90 day supply. There it is about $20.00. If I get it through my insurance I can only get a 30 day supply and I don't want to have to go to the pharmacy every 30 days and the co-pays would be about what the $20.00 is. However, I have asked about other medications there and they are as high as at other Pharmacies. Even the Pharmacist does not know why they have this particular drug that cheap. I have been doing this for about 7 or 8 years.
