Mail-order houses

Until round 1940 it was possible to buy a house by catalog. In 1908, Sears Roebuck started to offer house kits in their catalogs. The kit, which included the entire house, with numbered parts and instruction booklets, paint and nails. The first mail-order house is credited to Aladdin Company, who started offering the houses in 1906. I wonder if someone is selling house kits online these days.
