You can get them much cheaper than that in single and small quantities.
They are still quite affordable.
Many are "new surplus" and the like.

There is a burgeoning 1802 hobbyist community as part of the "very large"
CRAV Computing community. (Classic / Retro / Antique / Vintage)

They are very slow compared to today's microprocessors and microcontrollers.
So they are mostly only good for very specialized applications, existing systems maintenance,
and retro-computing.
