Marketside = WalMart

In the most literal sense. The new chain of stores called "Marketside" that's starting up is a rebranding attempt by Walmart, but they'll be run the same way by the same people.

As a friend of mine put it, for most companies, whether their public image is good or bad, when you take a deeper look at them, you find a lot of the image isn't true, and the real story is a lot more mixed. For WalMart, the more you look, the more bad stuff you find. Even if it appears they have cheap stuff, a lot of their "low prices" come from treating their workers poorly, making them work more than they're paid for, poor health care, and tax evasion. See more info at WalMart Watch. I have nothing against the free market as long as what's produced is clearly and honestly presented, but this is not a good business model innovation.

Anyway, my two cents... you now have more info, and it's your choice what you do with it.
