Here’s a smallish big box chain: http://www.valuecity.com/StoreLocator.do
Their store style & customer demographic is the same as KMart’s. Based on the stores here in St. Louis, they seem to be surviving just fine.
A little more rooting around on their website indicates they have over 100 of the Value City-branded stores, and a couple hundred other stores of other brands.
Not exactly WankerMart (thank you, Derf for the perfect name!), but still a respectable little chain.
