In the demo given, price per unit is $2000. The $2 are reservation fee paid through a cell phone / cc as a micropayment. 'Buying' doesn't actually happen, only reservations are made to 'participate' in the group purchase. After the deadline expires (the countdown timer), the item closes and all that reserved get a notification that it closed. Now the seller contacts all those (the admin side supports it), and tells them that they have 72h to purchase the item in the existing shopping cart with the discount code provided. That is of course if there is a shopping cart, otherwise an invoice or payment request can be sent, but that is however completely a matter of the seller. There is no mediation, only a reservation making tool that is easy to setup, use and configure. Thanks for the comment, I see how that can be a bit confusing.
