At present, Eager Zebra games primarily factor into promoting TripleClicks by encouraging those who buy from you to buy T-Credits. Games like Pick The Price have the additional advantage of encouraging activity in the Auctions, which also means the expenditure of T-Credits. T-Credits are a great mode for sales because there is no shipping involved and they can be used immediately, so if your customers like games, this can be a great way to earn commissions.
