walmart rugs
How good is walmart stuff for the home?

I want to know how good are they couches, rugs, appliances etc

It’s mediocre at best for furnishings and home decor items but that is what they are all about. We aren’t talking quality here and neither are they just lower prices. Appliances are what they are. If you like a brand and they are offering it at a decent price and it fits your needs, that is different. But I would certainly shop around for appliances. Many stores offer many more choices and good sales.
