How avoid reporting sales price in MLS?

[Hen Ley]

I've got a property under contract (as the buyer) and would not like the sales price reported in the MLS. I live in a non-disclosure state, so the MLS is generally the only avenue people have to obtain sales price information. The MLS imposes a fee to the agent for not reporting, for which I've volunteered to pay. However, the brokerage has decided they do not want to go against MLS policy and not disclose the price.

Any suggestions as to how to navigate this?  In my experience buyers often try to leverage your purchase price against you, so I'd prefer that information not be available.  This is in addition to the fundamental right to privacy for the members of a transaction.
