CashCrate - (CHECK) This site is very different, in a good way. You can do more than just surveys, you can also complete free offers. CashCrate has the most potential to earn money than any site and I help my referrals with monthly contests. Read more about this awesome site at Unlocking your CashCrate [INTERNATIONAL]
InboxDollars - (CHECK) There are plenty of ways to earn money on this site. They send email ads that are worth 3 cents each. You will need to click those to keep your account activated. You can do surveys, each one is now worth $.50 and you are only allowed to do one every 24 hrs. When you complete one, it should say this. [INTERNATIONAL]
Sendearnings – (CHECK) This is free site resembles InboxDollars in all but name. When you complete a survey, it should say this. There is a video on how to use InboxDollars/Sendearnings under Helpful Videos. [INTERNATIONAL]
OpinionOutpost – (CHECK) this is another good site. They give a substantial amount of surveys. It is a point based and those points are converted into cash. Be sure to log in to the members area often so you don't miss surveys they might have not emailed. [US; CANADA]
SurveySpot – (CHECK) The average amount they pay for surveys is $3. The great thing is they have plenty of surveys available. They also have sweepstakes-only survey but they tend to lend to paying surveys. I took one awhile ago and it asked me if I could watch a certain TV program and take a survey later about it for $25. Not bad. So be sure to do whatever survey they offer. Definitely worth joining. [US; CANADA; UK]
Pinecone Research - (CHECK & PAYPAL) You have to find the Pinecone banner on a random webpage to join. Just google 'Pinecone Banner' and hope luck is on your side. Once you are a member, you'll get $3 per survey and opportunities to test products. [US]
LightSpeedPanel - (CHECK; PRIZES; E-CERTIFICATES; & PAYPAL) Another point-based site. It is the MOST easiest site to qualify for surveys. You get a substantial amount of survey invites. I recommend this, you can make multiple accounts here. I had four active accounts for a year before they suspended them. It was totally worth it. I now rejoined with a new email lol. Just don't redeem points at the same time. [US; CANADA]
