OMG!!! The place is huge and I do believe their prices are lower than Costco's. Also, they have stuff that Costco doesn't have, such as bulk candies and such for sale. It was very interesting to browse through the store, but the negatives are that the parking lot is single lined and not double-lined like Costco. Double-lining the parking stalls gives each car more room to open their doors when exiting and re-entering with wagon-fulls of groceries. Another thing is that Winco does not accept credit cards like Costco, which is probably why they can offer lower prices (credit card companies charge a fee to the merchant each time a card gets "swiped"). Other than that, Winco is great and we really enjoyed shopping there today! I don't live near this store, but when I'm in the area I will be sure to drop by again. It's a fun place to shop!
