When I was buying my fixed address I remember seeing pricing for very small subnets like /20 or smaller.

A /20 has 16 times as many addresses as a /24. So I consider it large. The truly large are the /8 networks. Apparently is is fairly hard to "buy" globally routable subnets. The usual way of getting addresses now is to rent them from your upstream service provider. You can rent subnets smaller than /24 because routing is handled internally by the service provider. My /24 was assigned before the modern structure of assignment existed. It might even have been assigned by Jon Postel (I don't remember). I don't have an ASN.
