The Hornets currently have a Deal Threshold field on a rate card to say that "in order to add this item, the deal must be at least $100,000". We could do this through our approval workflow now but in their case they actually had this field populated on half of their inventory it looked like. Kind of a neat idea that we could use one day. Just thought I’d send your way in case it sparks any ideas.

Items would only appear once a deal has hit a certain threshold and if a deal drops below the threshold the user would be prompted to obtain approval.
