Lost PPC due to product catagory what are my alternatives to drive sales

I’m small time beer-money seller. Used to do about $1k a month when I was able to run PPC campaigns. Now I get about 250-500/mo. I sell martial arts training equipment but they classified it as a weapon so now I can’t do PPC. Can’t do Facebook ads for the same reason.

What are my other options for ads to drive sales?

Thanks.
