I am a member of A.W.Surveys, which is a survey site having more than 1.5 million members. I used to do their surveys and attempted to promote by joining referrals.The surveys are small ones and very easy to do. Actually it is review about sites in two or three sentences. One survey gives a pay of $1. If we are able to join referrals, we are paid $1.25 for each referrals. I promoted this site through different forums and my site and blogs
The most interesting part of this writing is that I got my first payment from this company, $50 to my account few days back, exactly on 09-08-2008.
