I like Winco but it's not the store I would go to on a weekly basis for grocery shopping. WInco offers a large selection without a doubt.
There best products for prices are produce, fruits, vegetables, canned goods, milk, eggs, and frozen foods.
Their meats leave a lot to be desired for us since we prefer higher cuts of meats that don't have by products or additives.
Their deli is minimal. I do not like the fact that they pre-slice a lot of their meat and place in front cooler for display. I prefer any deli meat to be cut to order regardless.
The store is massive so expect to spend a lot of time walking the aisles. The lighting is good, but check out can be a pain. Lately I have noticed they don't have many lanes open since the northerners aren't here right now.
You do have to bag your grocery items, which doesn't bother me at all. If you bring your own reusable bags I believe they give you $.10 off for each one.
They take checks, cash, or debit - NO CREDIT CARDS! I think this is also a great idea - every little bit of savings can be given back to the consumer :)
