How Did You Get Started Buying Expired Domains?

When I got fired from my teaching job back in 2013, that's how I started buying expired domains. So basically building out PBNs for this agency to link to their client sites. And you know, when I left the agency, I kind of took that with me and tried to offer it as a service back in like 2014. But there weren't as many services where you can just spin up several PBNs quite easily.
