I honestly didn't go into that discussion intending to be rude, but through their general incompetence they cost me an extra $140 last month, and they were getting ready to do exactly the same thing. She kept saying her system wouldn't let me fill my prescription for 30 days that it had to be 15 days. I told her that was ridiculous and that she was doing it incorrectly. She then told me, out of the blue, that I had never picked up my prescription on September 14th. I apologized that my time machine was broken and asked to speak to the pharmacist, who immediately fixed the problem. The root problem is that they change pharmacy techs about once a month. I don't know if they all quit or what, but they are always new and make a ton of mistakes. Every month it's something. And to make matters worse, Walmart is constantly in negotiation with pharmaceutical companies to get better deals. For a number of reasons, this causes Walmart to be in a constant shortage. At my next Dr appointment, I'm going to switch to a local pharmacy.
