93 del sol brake rotor

I was wondering if anyone knows how much a break rotor will cost me? Cause I heard that there is a hub or something that might cost me like $180..

Rotors are like $20-$30 each at your local parts store.

someone told me that if there is an extra hub on it then I have to get another part to do it and that is is like 180 for that extra part.... is there a such thing?

Someone doesn't know what they're talking about. Replacing the hub is completely different.
