Supermarkets now sell gas, prescriptions and have sit-down restaurants. Everyone is competing with everyone else.

You can let your stores grow old and tired for a period, but if someone comes in with brand new shiny stores and competitive prices, you'll go out of business quickly. They need to keep themselves up and invest in store upgrades.

Wal-Mart is the 800-pound gorilla. You're going to want to do more things for a customer who is growing as fast as Wal-Mart is.

Supervalu has offered to sell off its Cub Food stores in Chicago where it competes with (Albertsons') Jewel chain.
