The minorities might prefer shopping at your WalMart (in a white area) because they feel it is better than the one in their neighborhood. It’s the same as poor people window shopping at a jewelry store. They want some of the riches to rub off on them (somehow). So maybe they get a psychological lift from shopping at your Walmart
The US history of white moving out of cities and into suburbs is that minorities will follow. Yonkers was a great white flight suburb 30-40 years ago. Now it is heavily minority that have moved out of the Bronx. Atlanta George will give even more examples of white flight then minorities (blacks) eventually following them

And they would be correct. I’ve found that Walmarts tailor their merchandise mix for local shoppers. I see a fairly significant difference between my local Walmart that is apparently catering to a fairly sizable contingent of illegals, and Walmarts that are 30 minutes away in communities that have fewer illegals because the bulk of nearby neighborhoods are more upscale. Those distant Walmarts carry better quality, more expensive goods than my local Walmart.
