I use CVS but only because it is nearby and has easy parking. Besides, there aren’t many alternatives in our area, despite its being densely populated. The giants have gobbled up or pushed out most competition. It is disgusting how concentrated the pharmacy business has become. CVS has the worst IT department I have ever encountered — harassing and useless — but apparently believes it can get away with such poor service. Pharmacists rarely answer their phone, yet mistakes in prescriptions are rampant. Worse yet, I recently learned that even getting insulin pen needles was becoming difficult, with significant delays. I asked whether Walgreens was any better and was told that CVS and Walgreens get pen needles from the same distributor, so they are suffering the same delays! We seems to be becoming a third-world country with respect to reliability of supply (including energy supply –we routinely now have unexplained power outages). I believe a lot of this is due to the anti-competitive consolidation that our government has allowed to take place in a variety of sectors of the economy. Any economy of scale benefit is eventually outweighed by the consequences of lack of competition.
