QuickRewards is one of the best GPT sites out there. It only accepts members from US, Canada, and the UK and membership is free. You can earn money a number of ways from this site. I have listed those down below.
1) You can complete surveys from their surveys menu. Once you successfully complete a survey, you get the amount for that particular survey. Sometimes you receive an e-mail invite to do a special survey from them which is only available for a limited time. My suggestion is for you complete these types of surveys as soon as possible, I would say within a half an hour from receive the e-mail invite. You also earn tokens from completing the regular surveys from them, which you can redeem them for gift cards if you become an elite member. To become an elite member at QuickRewards, you must either complete 75 surveys in a quarter or by making 5 purchases within their site in a quarter . You can cash out with no minimums from their site. You get paid by Paypal.
2) You earn money by shopping from stores through their site like Ebay.
3) You earn money by clicking on ads.
4) You can earn money by completing offers.
As you can see is very easy to make money from QuickRewards. I have been paid many times from them by paypal. Once you cash out, you receive the money in your Paypal account within 48 hours from requesting it. The site is very legit and I have never had any problems with them. Always pay attention to their site as there are things happening every quarter in their survey section.
