For a cost of just one coffee and 5 minutes downloading picture they can get some nice prize and still if they did not win, then can get some nice item at least once in a year from TripleClicks Store.And anyway as their Sponsor you could give them a 2$ Gift Certificate and just get them into this program easily.So, they already signed to be affiliates why they could use all the possibilities what SFI gave us to earn some income including WAVE3 Program.
