Facebook Ads Course

Hi! I just became a Patreon a few days ago. I’m just beginning to dig through all the resources, but so far I’m really impressed! I do have a more specific question though and I’d love some input.

I am having an awful time with my Facebook ads. Everything was going well until last September and then it’s just been a mess. Every time I think I have it figured out, something changes again and my sales tank.

I’m considering paying for a new course from a pretty well-respected author ads guy, but it’s close to $700. Is that ridiculous? Is there a way I can just figure this out myself? Does anyone know of any really good, up-to-date resources?

Thanks so much!
