Can you advertise anything regarding commission?

[John Apple]

I am a new agent who is finding it difficult to get my first listing. I recently started running ads and I'm wondering if it's legal to say something to the effect of "I can save you thousands on the sale of your home". There is nothing misleading about this, since I would gladly reduce my commission in order to get a deal. Also, I read the NAR ethics and advertising guidelines and found nothing that said this would violate. The only thing that concerns me is that I have never seen an ad like this. Is it just because most agents don't want to cut their commission or am I missing something in terms of legality?
