The Wal-Mart Effect: How an Out-of-town Superstore Became a Superpower Paperback – 20 June 2006

Useless for entrepreneurship, its the story of how Wal-mart dominate the whole market, repited all across the book. That's it.

excellent

It was a really interesting book to read.

Good read, but the info was too old (10 year out of date). By now Walmart are a whole new organisation and much larger. So it's for history buffs only.
