Quoted from CrazyLevi:Wal-Mart probably wouldn't want to put a pinball machine in each of their lobbies. They'd take up valuable space, they'd be a maintenance nightmare like all pinball, and they'd likely lose money on each machine. And most importantly, people who are playing pinball aren't shopping.
wal-marts did have pinball's on coin play back in the 90's I don't think they owned them.
