That's a big number right there. And what will happen if you guys fail to fulfill such promise?
'Cause for this "online store" to work, you need lots of people visiting and making purchases in it. You know, high demand. Without those, you can't really promise such big ROIs.
BTW, are the products that get listed here, all of it will be from you guys only? or any other user can freely list their own product?
Lastly, how will you ensure that the costumers are free from fraud? That the item purchased will be delivered?
