Walmart finally got the message and greatly upped their online selection of goods to choose from. Their early online goods list was paltry compared to Amazon.
I first go to Walmart online, then I try Amazon if I don't find what I'm looking for. For generic items, Walmart online has what I need, it's only with the more obscure items where I have to look farther.
Sears is a fascinating story.
The Sears catalogue was Amazon. It sold everything you could want and would deliver it to your door. For most of the 20th century it was how most Americans bought most things.
They shut down the catalogue in 1993. A year before Amazon launched.
It was a trillion dollar mistake.
