upselling??

[bostoneventguide]

Looking for a plugin/extension or some way where after a person makes a purchase they receive an offer to get their purchase free if they get "X" amount of other people to make the same purchase. I'm thinking it'd be a combination of an affiliate program and a points system. Is there something like this that exists or possibly in the works?
