My husband fills his meds here, and has never had issues. They have always been very nice.
I do have a question if anyone can answer. I took my prescription in and they tuned me away, and they said they didn't have it because the state only allowed them to have so much of that drug. Then when my husband went they filled his no problem. We take the same exact medication. I was trying to get us into the same pharmacy for convenience. Is there something I have to fill out to get my prescription filled there?
