It seems that CVS has numerous problems -

"We receive many serious complaints about CVS pharmacies filling prescriptions incorrectly, losing prescriptions, dispensing the wrong quantity of pills and generally mistreating their pharmacy patients,..."

CVS made an error with one of my meds recently too. I received a med for nausea and I was unfamiliar with it so I read info online. I learned that the oral dissolving version is not supposed to be removed from the foil container until immediately before used. Mine were already out of the foil sitting in the pill box. At $10 per pill you would think they could get it right. Not a potentially fatal error but it still could affect the efficacy of the pill and when a single pill costs $10 you really want it to work properly. I am going to complain to the pharmacist who filled it and ask him why he decided to dispense it that way and make it clear to him that the only time he fills my meds is when I am really, really sick and can't make the 45 min trip to Walmart.

Walmart though I LOVE as a pharmacy. I moved all my prescriptions to Walmart after an incident with my then pharmacy. I did not realize it but the previous pharmacy was charging my son $14 for Seroquel because it was one of their program drugs and when I filled it at Walmart I did not know that it would cost $250. Because the external labels only list the rx # and price I only knew I had spent $700 but didn't know for what. I cried when I got home when I realized I had spent so much for the Seroquel. I called the Walmart pharmacist and asked if there was an error since the med was so costly but that was the actual cost. I told him I didn't realize the costs of each until I opened every package at home and he was soooooo nice to me. He said that because I was new to their system he would make a one time exception and allow me to return the Seroquel for a full refund. I cried on the phone. He could not give the pills to others because they were not package sealed but he took the loss to help me out. That is a good pharmacy.
