What sucks is how WM has moved in and shut down local stores and smaller chains... eliminating competition (and shopping options) for many of us, particularly in more rural areas.
That dog doesn't hunt anymore.
What usually happens is that the employees or owners of the mom and pop stores become department store managers at Walmart in their specialized field. Also, there are higher-end, specialty stores that are built next to or in the area of Walmart as well.
