I cannot for the life of me understand why Sears didn't become a major online retailer. They not only had a physical catalog system that could be fairly easily converted into an online catalog, they have physical stores that could be used as pickup points and warehouses for customers who don't want to wait until things are mailed.
In the UK there's a company called Argos that worked ENTIRELY as a catalog store. Their physical locations were basically a warehouse with a lobby that had the catalogs and computers where you could look items up and order them. THEY should be a major competitor to Amazon... but according to my UK friends, they're not.
