Where is the most profitable Walmart?

When I went on a cruise to Alaska, the tour guide told us the Ketchikan Walmart was amongst the 10 most profitable Walmarts, it sold out completely from ALL of their inventory in 2 days, since people from remote areas of Alaska will buy in bulk because they will come only once a month for food and necesities.

Another Walmart that's amongst the 10th most profitable is the one in Calexico, CA a small town bordering Mexicali, in Baja, Mexico, where the bulk of their business comes from.
