WujWuj will assuredly fail like everything else similar because they require so much interaction for a product, too much hunting, and everyone always wants the lower price.
Solution, offer the rebate later. Go ahead and shop buy anything you want and share what you bought, brag about it, get others interested, but don’t wait for the savings.
With your online account tracking your history, anyone in your network, according to your setting of filters and privacy, can review some of the favorite items you’ve saved on or bought lately. If they are interested too, they can go get it. Say one hundred people in your network bought Super Bowl memorabilia for full price, well according to WujWuj, if they had bought it through their group buying, they would have all saved 20% if they waited and bought together. Well you are still a group and you all still bought the same stuff, so why not still get the savings. This is possible if you offer the savings later after the purchases have been made.
You can still promote the things you buy and attract more people to your purchases, thus still taking action, and therefore still applicable towards recieving savings.
