They invented almost all of that a century earlier. Amazon improved their warehouse management and, later, delivery times but that happened later. If Sears management had been earning their pay in the 90s that would have been much harder because Sears had a huge inventory and unmatched local presence for returns, support, etc. if they hadn’t been AWOL moving the catalog online. Amazon was shipping at regular postal speeds then, too, so Sears could even have beat them if they shipped from their warehouses.

This wasn’t uncommon back then: we had several clients in the 90s who just couldn’t wrap their heads around how quickly many of their customers would switch to email or online forms when it saved them a few days on the transaction.
