In reality, there are so many reasons I dislike Wal-mart, that I don't think I could list them all. Let's start with inferior products and dirty stores. That's enough reason to keep me from going there. Sam Walton's stores were packed with "Made in America" signs, now Walmart stocks mostly things that are made in China. Or maybe it's the strong-arm tactics they've used with companies to lower prices, lowering quality and hurting other companies in the process that makes me despise them.
I'm a shopper and I like a bargain, but I don't think that what we're getting at Wal-mart is a bargain. Check out this video, which was linked to by Scott for a look at an amusing take on Wal-mart's "low prices."
