Wal-Mart to Test Small Store Format

Wal-Mart said it would introduce a small-store format, called Wal-Mart Express, aimed at rural and urban areas without nearby grocery stores. The first prototype store, set to open this week, stands 15 feet to 20 feet tall and has 45 parking places — a big change from the typical Wal-Mart superstore with high ceilings and vast parking spots.
