I don't see anything obvious about that at all for amazon in the book selling days.
dog food is heavy, and a repeat purchase that often requires its own store and brings no joy. Its the ideal thing to get delivered to your house on a schedule.
books are something you choose differently everytime, and the people that like them read recreationally.
Bezos was on another level, launching a successful company(online books) that was effectively just a way to boot strap into an everything store.
It was actually even smarter than that. People also forget about "media postage" rates that existed at the time. (They still exist, just fyi)
In 1999. To ship a book using media mail cost of $1.13 for the first pound and $0.45 for each pound up to 7lbs. It got cheaper per pound above that.
This meant even heavy books were relatively cheap to ship. Way cheaper than random goods.
Wasn’t one of Amazon’s biggest advantages over brick and mortar stores the fact that you could effectively avoid sales tax for a lot of the purchases?
I heard that's why Washington state was chosen. Close to tech talent (Microsoft was there) and fewer people living there than other tech-heavy states such as California, so the US tax-exempt market was larger from Washington state.
I believe ChatGPT or Anthropic are both trying to be the "everything store" - whatever that may look like - of this brave new world. Call it a "business OS" and/or "life OS", they're clearly aware that research alone won't win dominance, and signs have been cropping up for the last year: Cowork, Research to Artifact pipelines, Dots/Instinct/Muse-esque personal assistant alternatives.
But the counterpoint still translates here: Amazon did not start with 1000 warehouses (i.e. Anthropic's debt obligations) and _then_ race to build a marketplace that would fill them with everything under the sun. It started lean and mean, and I suspect the Anthropic-killer will do the same.
