There's a positive one from convenience-sensitive shopping too. > then Amazon would just set its prices 1/.6 = 66% higher than the other stores. And such would be the price of convenience. I shop at Publix and pay the higher prices over Kroger because Publix is 5 minutes away from my house whereas Kroger is 10. I don't do major grocery shopping as I'm single. I'm happy Publix exists and if everybody were so price sensitive they'd drive to Kroger instead, Publix would go out of business or lower the quality of their services so they can compete price-wise with Kroger. Having multiple store options available diversifies not just the market for goods, but also the market for shopping experiences. Price-sensitive shopping, if everyone did it, would absolutely lower prices for everyone, but ultimately would reduce options. I would hate to live in that world. I bet that Kroger has a better, more convenient experience than it would if Publix wasn't there, simply because Publix is an option. Kroger does have self-checkout lanes and nice decor, just not as nice as Publix's.
