Safeway in Oklahoma was long ago was spun off to it's own chain, Homeland, which is now gone from Tulsa. Reasor's bought out the Tulsa area Albertsons stores, I'm not sure what happened with the OKC area Albertsons stores.
I don't feel I have a lack of grocery stores to choose from. We mostly shop at Reasor's and Target, but within about a 10 minute drive we also have Walmart, Sprouts, Whole Foods, Fresh Market, Aldi, Sam's, Costco, and various Asian and Hispanic markets to choose from. I don't know Winco. There's also Warehouse Market chain, but I don't know of one close to me.
Winco is from the west and finally moving this way! One of the kids worked for them for a while and thought very highly of the place - it is where they shopped as much as possible! Only left due to a move to MN.
While in OKC I would go there quite and bit after they opened up a few years ago and it was excellent! Really like it a lot! Have been a few times here but it is out of my normal traffic pattern and I "forget" it is there! Got to reprogram some neurons!
