When I first started coming to WinCo I would walk through the isles and marvel at how much lower the prices were on the exact same items I was buying elsewhere. After a couple years my jaw doesn't drop anymore, but I am still pleasantly surprised by the lower prices.
It becomes apparent where WinCo is able to save money: warehouse style, bagging yourself, no credit cards, limited variety of items. These are all fine with me, but don't get hung up on the variety. They still have name brand, not just every kind. 1-2 name brand and 1-2 generic variations per item.
Their produce is always terrific and so much cheaper than other places. How can they get away with selling bell peppers so cheap? They also have a great bulk item selection with items you wouldn't expect to be sold by the pound. Individually wrapped candies, croutons, big sugar-free candy selection.
Great place, I just wish there was one in Scottsdale.
