Freezing your credit is free. Unlocking it permanently or temporarily is also free. If you ever pay anything (yes, even "only" $10) to do any of this you're doing it wrong.
Yep, just like when you get that paper in the mail to renew your LLC every year and it's only $110. It's $10 to the state and takes 2 minutes online. I hope nobody falls for that one, but I'm sure they do.
