I would like to be able to bundle forge products for a discount. Any thoughts on this for the future?

Independent of that I would also like to be able to offer a group discount. This came up with my extension UpDEnhanced because each member of the group requires their own copy. I would like the GM to be able to buy say 5 copies and send in four names selections with that. The GM pays say 3/5 (flexible cost) the cost of normal and then gets a copy and the four selections also get a copy. The group then pays the GM however they want.

Thoughts?
