Technology can't create a value proposition where none possibly exists.

There was no Pets.com business model that would have worked, with any technology shy of a free energy transporter.

In contrast, Amazon proceeded thusly.

1. There are a lot of people who buy books.

2. People who buy books would value a wider selection. (than current local options make available to them)

... therefore, what combination of technologies exist that allow Amazon to deliver on the above? (web storefront + centralized warehousing + efficient shipping)

The point of bubble businesses is that the first two components, neither of which have much to do with technology, are often absolutely missing.

Fundamentally sound business plan + new technology >> ?? + new technology

Too many bubble businesses are the latter, and people invest in them despite the ??.

The Pets.com business model is essentially the same as Chewy, which does work. As far as I know, Chewy has not discovered a free energy transporter.

Chewy is Pets.com + being owned by one of two major pet related brick-and-mortars + diversification into vet and pharmacy services.

Chewy was already a multi-billion dollar company by the time it was purchased by PetSmart. Chewy is now publicly traded at a value of over 16B.

Not sure what your point is regarding vet and pharmacy services. Businesses expand. Pets.com, had they been successful, would have likely done the same thing. To use your Amazon example: obviously most of Amazon's revenue is no longer generated by selling books.
