The only Walmart here is a superstore. I don't like it but need to go there regularly. It sure beats the Target a mile away. Their pharmacy is kind of strange. My wife had knee surgery a few weeks ago and they don't sell oxycodone. We go to Costco for that. On the other hand, my wife had a diabetic dog that needed daily insulin injections. Walmart's price on insulin was 1/4 the price of any place else in town, $26 vs $95 for a small bottle. Seems that Walmart owns the insulin factory, literally, and they sell it at a greatly reduced price.
Amazon has a full pharmacy.
