I use SignNow.com - the level of subscription I need is something like $8/mo.

However, I probably use it less than 1/3 of the months that I pay for. This is true for dozens of memberships: Adobe, Canva Pro, Netflix, HBOMax, The Economist, etc.

It'd be nice to have a service that automatically unsubscribes me after every use, but rejoins seamlessly the next time I sign in.

If I pay for a month of Netflix on Jan 1 and immediately unsubscribe, I'm good to use it until Feb 1. If I don't log in for a week, it'd pay on Feb 8th and unsubscribe again. I'd have til March 8th to watch, and I'd save ~25%. For less frequently used services I might save 50% or more this way.
