Those are the ad items, but it is a locally owned 1 store operation. Father and son run it, with lots of employees. They have the only grocery store in the county, but are competitive with the big boys in Abilene (60 miles away).
Many food items vary a lot because of transportation costs (particulary on produce), also cost of doing business. Texas is business friendly.
Texas is fantastic. We spent a few days driving through from the Louisiana side to the New Mexico side years ago and loved it. I had never seen anything like that in my life except in movies. I got out of the car in the hill country,looked out over the land and shouted “Yaaaaaahooooooo”!
