How do vacuum stores stay open?

Seriously folks, how the hell do vacuum stores seem to stay open? I think one or two in the city should be enough, let alone the bigger stores like Canadian Tire and Sears, there's also Wal-Mart and Zellers. Do we really need the smaller stores? Does everyone in the whole city need a vacuum? Do people even vacuum anymore? Like seriously, how do vacuum stores seem to stay open???
