Donation box to pay for an item in commerce

[Mark Round]

Hi I'm not sure if this is available but I've been thinking about the idea of offering people a choice on what they consider a fair price for a product . Kind of like an honesty box or donation box if you like this would be coupled with the option of allowing a minimum amount payable if necessary. Is this kind of thing possible? Could it be made available here as a trial on invision market?

Sounds cool. I support.

I could see this being a plug-in but not a full blown feature integrated into IPS
