That's new. I didn't know I could buy points from those who make them and transact them between other accounts.

Funnily enough you actually can with airline points and there are websites dedicated to this economy of getting points then selling or transferring them to another airline where they are more valuable or useful (Singapore Airlines’ KrisFlyer program is very popular).

Not just airlines, but other types of points or even Amazon gift cards.
