Audible alternatives?

I'm not too familiar with what's normal in terms of pricing in the audiobook world, but Audible seems so so expensive! Am I crazy, here? Like, each book is one credit, right? And $230 a year gets you 24 credits, so just 2 books a month? Again, maybe this is totally normal and I'm just poor lol, but it seems pretty dang pricey.

Does anyone have other audiobook services they can suggest??
