I think the price differential here in the New York metropolitan area might be a little more pronounced.
I can't honestly say I buy a lot of health and beauty-aids type items, but I do buy their diet soda! The Sam's choice brand is 58 cents a bottle, unlimited, tastes good, and I do stock up....supermarket brands aren't nearly as good, and Pepsi runs 79 cents-$1.19 on sale, maximum four bottles, regular price $1.49....so it adds up. I'll buy "George" slacks, sweatshirts, socks, and the like....the stuff isn't bad compared to everything else out there, and the cost savings are substantial. For plain-vanilla type music and supplies for my light sculptures, I wouldn't buy anywhere else. Their small electronics are horrendous, but I'm told the new ILO LCD television sets represent very good value, and I'd buy one if I needed another set. Probably the biggest savings I realize is gardening tools and flowering perennials, bushes, etc. The nurseries in northern New Jersey are very expensive, and believe it or not, the Walmart stuff never dies on me!
The sales associates in Secaucus range from surprisingly helpful to just okay, but better than in other Walmarts, and I get around the customers jabbering by wearing my Walkman earphones and listening to music while shopping.
Not nuts over their laundry products selection...I'd rather hit Costco for that.
It's not everyone's cup of tea, but, to a certain extent, WalMart works for me.
