Well yes the rewards for referring people are nice, but I would have told about this site even if I wouldn't get a reward. To say that I am only doing this for personal gain is not a statement that you have the knowledge to make (unless you have met me and have found me to be a greedy and self-centered person, or else you have a mind reading machine trained on me). As for being a waste of time, that depends. For some, RS membership is super cheap and not worth spending time getting it for free. But, If you like the offers on this site and want to save cash, why not try it?
