Looking around, Jellyfish offered the best cash back for an upcoming purchase I am planning. Surprisingly there is not a conga going for it already. They offer the referrer 1/2 of their profit for the first year (without cutting into the referee's cash back amount). Anyways, they need an e-mail address to credit the referrer, so if you are interested in joining, use the link below and PM me for my e-mail.
