WinCo is conveniently located in the heart of Temecula on Winchester Road. It is a huge super market with an extensive selection and great prices. WinCo is a cross between your average grocery store and a wholesale store like Costco. It has everything you would expect from a grocery store including a produce section, a butcher, seafood, deli and liquor. Its bulk food section has three large aisles where you can buy anything in bulk including pastas, cereals, coffee, dried fruit, nuts, candies and snacks. You can even make your own peanut and almond butter here.
