One thing is that Trader Joe's has a much higher profit margin on their produce. Its customers are willing to pay these because they like the tradeoffs of good customer service and the stuff that the store has. Walmart's customers are not willing to pay that. They're willing to deal with no customer service and bad quality for rock-bottom prices. It's a big difference that showcases the two business models. When I know exactly what I want to buy, (A thing of Lemon Pledge, some Worcestershire sauce, and a package of cue chalk) Walmart is wonderful. When I'm not quite sure, a store with good customer service beats Walmart every day. I would never buy a bicycle at Walmart, for example.
