IIRC, when I used it for my employer .com was $100/domain year, registry lock for eligible tlds was $1000/domain year (I forget if that included the domain), and there was a minimum annual spend that I don't remember, but might have been $10k-$30k. They have new ownership since then, so I dunno.

The only issue we had was when we wanted to change our nameservers and our authorized contact for registry lock didn't answer the phone for the verification call, so we had to postpone the change for the next day. But that's what is supposed to happen, so no big deal.

Better than networksolutions changing our nameservers when one of their support agents got phished.
