Yes, for random consumable things mostly. I buy stuff like Command hooks, toilet paper, shower curtains, light bulbs, shampoo, generic Advil, etc. Food is hit or miss--my husband hates the milk and ice cream, and their produce and bread always go bad too fast. But I adore their store brand prepackaged fruit snacks "Fruit Smiles", and some things I can get much cheaper than our regular grocery store: tuna fish, salsa, canned soup. My current Wal-Mart is patronized mostly by recent immigrant families, so it has some pretty decent Asian & Middle Eastern products I don't see elsewhere. The checkout lines can be long, unfortunately, and shelves are sometime not restocked in a timely manner.
I grew up poor in a small town, and remember everyone I knew being genuinely excited when Wal-Mart came to town. My mom could feed four of us on $30 a week there. I once went into a Target behind a woman and her little girl, overhearing the daughter say "we don't like Wal-Mart, right Mommy?" and the mom responded "That's right, we only shop at Target". It was weird, and had all these strange classist undertones, but this preference for Target seems to be a common phenomenon.
