I'd like a nostalgic Sears, Roebuck & Co. store, but I don't see Menards offering a model of a company that is a competitor (a very weak competitor but still a competitor that sells some similar products - hardware, housewares, outdoor/garden equipment).
IMHO the best option for a nostalgic retailer such as FW Woolworth, SS Kresge, GC Murphy & McCrorys would be Andre's River Leaf Models . You could also make this structure into a Montgomery Wards or any local retailer that fits your era and locale.
