A lot of hosting companies have decided that selling ssl certs at inflated prices is a nice side business. I used zerossl (kind of a LE front end/spinoff) for a few years, it had free 90-day certs that you could manually renew, then it changed to maximum 3 free certs a year. When I got a paid cert for one of our work domains, because hosting doesn't support client cert management, I discovered it was a zerossl cert.

Anyway I switched to letsencrypt when I upgraded our staging server to a more recent version of ubuntu, one that supports the "certbot" auto-renewal script.
The cheapest *not free* certs I've heard of are from gogetssl which IIRC are a few dollars/pa.
