Big box stores

On Chicago's west side, 25% of competing businesses within a one-mile radius of a Wal-Mart went out of business within 12 months, and 40% shut down within 24 months.

If you think Wal-Mart would just plop down a store or two in East New York and call it a day, you don't know Wal-Mart.

The largest increase came from Manhattanites, who spent 26%, or $65.1 million more at Wal-Mart than they did last year.
