I used to think that Amazon was nuts, going from book sales to ... well, to everything else! I thought they would crater, because who would go to Amazon to buy clothes or electronics or barbeques or cameras?
The jury is in and I have been found to be phenomenally ignorant on the topic! But, never accuse me of not jumping on a bandwagon once it gets going. I now buy so many different things (or at least a high percentage of the things I buy at all) on Amazon that it is ridiculous. Books are the start, for I have a Kindle. Why so many of the other things, though? Because they have made the shopping experience the easiest and most efficient on the planet.
With one click, I buy something that is automatically charged to my credit card which is on record and the item is mailed to my address, also on record. I love waffles for breakfast, so I have a subscription to a waffle mix called Kodiak Cakes, 6 boxes of which automatically ship to me once every three months. Once every two months, decaf coffee for our Keurig coffemaker automatically ships. It is easy and the prices are usually very competitive.
Of course, there are a few downsides. It, like Walmart stores, is killing the neighborhood shopping experience. Killing the neighborhood shopping experience is to some extent killing the sense of community. Killing the sense of community is making us more isolated and leading to less employment. Shopping for a book online has none of the warmth of shopping for one in the neighborhood bookstore.
Who would have thought you could do all of that with one click??
