Had no idea. I do appreciate this. I must of missed the 'splainer. I'll remember that for next time.

Just FYI, you can remove all the parameters from Amazon URLs and they still work. EG: https://www.amazon.com/Fluent-Python-Concise-Effective-Progr...

You can also emit the title: https://www.amazon.com/dp/1491946008/ works fine.

And yet another trick for shortening Amazon links: http://amzn.com/1491946008

But then the same question as with other short URLs appears: Does amzn.com really belong to amazon.com, or is it a third-party service that may redirect you somewhere else at will?

The point is, I don't care whether amzn.com really belongs to amazon.com or not. I want to check a domain quickly without having to research that kind of stuff.
