It depends on the item.
At the grocery there are certain items I prefer brand name. And others I have no problem with generic. We hit Walmarts, Krogers, and Aldi. But I gotta have good bread to make me sandwiches. None of that off-brand stuff that is stale in a couple days. It's gotta be Pennington or Swebels baby!
When we bought appliances for the house that get a lot of use I go with products that have a reputation of durability/reliability. Our washer and dryer are Maytag Neptune front loaders.
So I don't mind spending extra for quality and longevity.
It's why my cars are Hondas.
