I haven't. That's not the point. Nor is the specific commission an agent receives. If a realty agent can get a 33% commission for him or herself, than by all means, go for it. I'm not asking for realator's fees to be limited.
My problem is that the realator's associations are trying to get laws passed to mandate a specific commission, rather than letting the free market decide what those commissions should be.
Please cite the case or example in question; I know that the NAR is in favor of the free market system.
