Even if you don't do the majority of your shopping at Winco (and you should) at least check out the bulkfood section. Because you aren't paying for all the packaging and advertising of brand names you can save a ton of money on items like popcorn, raisins, nuts, and most of all spices.
I have been shopping at different Winco's for years and wouldn't do most of my shopping anywhere else. I prefer the Hwy 99 location after a bird on the produce incident at the Winco on Fourth Plain and Andresen. I would also try not to shop on the first weekend of the month because the store can be really crowded.
They now accept debit cards and they also accept manufacturers coupons.
On the way out with your cart full of groceries (for 1/2 as much at other stores) be sure to get a slice of yummy pizza. Its a large slice and includes a drink.
