Supermarkets can probably only do this to a very limited extent. Moving entire aisles of product has a large human labor and training cost they would need to pay for, not to mention physical space and plate wiring limitations. They can't just chain a few code blocks every time some one gets a bright idea. I will say costco will often move a product I regularly buy to an endcap to put it on sale. Then I can't find it anymore and am unable to buy it that week. I've tried asking the employees where it went but they never know either. Now I do a brief scan and then give up. For all I know they stopped carrying the product entirely.
