This is a very good question.My answer to this is that encourage your affiliates to take part in daily T-Time drawing contest,in this way not only they get one versa point,they also get chance to win 2Tcredits,which they can further use for auctions.Moreover they can sell their unwanted things at tripleclicks.And the biggest advantage they get is that tripleclicks offer more than 100,000 products at a discounted price to them.so there is a win-win situation for them.
