You should get a library card and the Libby app. Lots and lots of free audiobooks.
I read kindle versions, but there are almost always audio versions of everything I read. I read a ton of SF and fantasy - if you tell me the kind of stuff you like I can suggest some titles.
A couple years ago, after I sharply increased my reading, my wife (who paid the bills) came and said, "I don't want to discourage you at all from a healthy hobby, but I wanted to make sure you realized that, in the last couple of months, you've spent like $200 on books." In fact, I hadn't realized it was that much. That's when I started trying to figure out a cheaper way to read.
I read even more now. So far this year I've read 46 novels. That would be prohibitively expensive if not for Libby.
