I like Surveys.com because they always send out surveys that usually pay better than most other sites (around $2-$8 per survey) and since you fill out a profile for them beforehand, you will qualify for a high percentage of the surveys that they send you. Payment from them is directly to a PayPal account, so will need to set one up before joining them, and payment does take up to a month sometimes, which is kind of slow for PayPal payments, but not to worry, because they are still a great survey site. Surveys.com is also interesting in that they allow you to see a lot of products before they ever come out. Their coordinator, named Carole Henderson, is a very helpful and knowledgeable person that will answer any of your questions usually within 24 hrs of you sending her an email, which is rare in the survey industry. They do have a referral system, but I am not sure what the incentives are, as they do not outright come out and say what they are. Anyway, there is no specific link for signing up through a referral link, but luckily enough they were gracious enough to give me one so I guess I have fallen into their good graces. The send only 2-5 surveys per month, but they are well worth it!
