You have chosen to sponsor your bid up to a maximum amount of .
I want to build an ecommerce website where users have the power of commerce!
The administrator post an item like "Iphone 5" and a starting price like "800$".
After, the administrator set how much price decrease for one more user that join campaign.
So the result is break down item price when number of users increase.
Sellers can see the campaign and choice to sell part of customer items reserved.
Admin post: Iphone 5 - 800$ Decreas to 700$ when users arrive to 100.
So 100 users ask to sellers to sell 100 iphone one shot for 700$.
Seller can choice to sell all 100 iphone or part of 100.
