Walmart has done something similiar. Targeting where to build its store, usually on the edge of a town where land is cheap but traffic is high. Then stores build around the Walmart. Walmart buys big lots, like a former farm, and then sell/rents the lots around it to these other stores. It makes a lot of money doing this, because it buys cheap, land that has little commercial value, let's say for $100,000 and acre. Then it build a Walmart on part of it, and the traffic to the location is now huge. It then sells the lots around the Walmart for 1,000,000 an acre. It's a big sidebusiness for Walmart. In every small town you will find this to be true. In sprawling urban centers, Walmart has to buy in the middle of developed area and couldn't always use the same tactic, but had to get stores closer to consumers.
