If you're still around, here's a particularly ludicrous example from my own life.

I'm interested in using one of Martha Kolln's books to teach myself grammar. These are college textbooks.

I can't purchase the teacher's edition, which means I can't check my work against the correct answers.

I'm a middle-aged person interested in learning grammar from one of the leading scholars on the subject, and I'm out of luck.
