You hit the nail on the head. Whenever a new Walmart pops up there are at least a half-dozen smaller, specialized shops that spring up next to it.
Here in De Pere, Wisconsin (a suburb of Green Bay) a Walmart Supercenter opened up - there are also plans for a Menards (home improvement store) and there is a gas-station island with several fast-food chains.
Liberals absolutely despise Walmart.
As far as our Wally world in Nampa, ID. It popped up and there are new stores popping up all around it. Most of the grocers are still here as are specialty clothing shops. We didn't have much in the way of general goods except a few Farm Goods and other supply type stores. All are still around. The only ones that aren't are the ones who were dying before Wally world came in.
