Free / open pricing - choose what you pay for Claim Pages

It would be really convenient to have the ability to propose free pricing (with an optional maximum and/or minimum price options for more freedom), that could work as a tip for those willing to tip, and cheap or free editions for those who cannot.

I agree, I was thinking it would be cool to do an edition and give buyers the option to pay what they want. Is this possible or can you guys add this option?
