It is a shopping website, but it does not sell anything. Simply lists the best deals and sales it finds in many major US retailers.
Social shopping part (user submissions) are ready but not sure when it will be enabled yet.
One important thing I am not completely sure about yet is the listings sort order. Right now it sorts by savings percentage plus actual savings amount. This so far to me seems the best and most natural sort order. however, what if sorting on savings $ amount makes more sense to the user? So a product where you could save 500 dollars and is 10 off is before anther where you have a 100 dollars savings while the percentage is 50%. I don`t know if I managed to explain it clearly.
