Wal-Mart, is it a necessity?

I've been pondering this question the last few days...and I think that after the past year, I can feel confident saying "no." For many, many years I jumped into the car and took off to Wal-Mart for everything from frozen vegetables to toothpaste to hosepipes and underwear. But I first noticed I had a choice when ALDI moved to town. Specifically, right next door to Wal-Mart. Then I realized that I could buy groceries elsewhere without upsetting my routine too terribly. As the months passed by with my mind being opened to options (and enjoying the freedom of not standing in line for an hour) more shops moved to our little town. Target and Publix opened their doors and my choices grew even more. Finally I feel confident knowing that the few things I wanted that ALDI didn't sell and Publix was to pricey for, I do have Target. I took the time to actually compare the prices on t-shirts, toys, dvd's and the like, and find that Target is a smart place to shop! Wal-Mart has been telling us they are "the low price leader" for so long I had begun to believe it without question!
Don't get me wrong, I'm not out to put Wal-Mart out of business, (like I could) but just to show you that, yes, we do have choices! My Sam's club membership renewal came this week. Now I'm trying to decide if I even need to bother?
I would love to hear any comments you may have!
