I personally like this one for some spare cash. It does not take much to earn an extra $20 – $50 a week. Some claim that they are able to make a living by dedicating their time to different jobs at mTurk. You will have to go through a learning curve, but once you get comfortable, you will find plenty of good and interesting HITs (Human Intelligence Tasks) to work on.
One of the great things about the Internet is that it can connect people and companies almost instantly, and companies have found out about it. Companies have found that they can receive almost instant feedback about their products, services, or ad campaigns through the Internet. This is called market research, and before it used to take companies hundreds of thousands of dollars and many months to find average and sometimes outdated data.
Worth noting is that Postmates doesn’t even require that you deliver by vehicle — a bike will do. Better yet, there are no startup fees or time commitments with Postmates and all you’ll have to do is pass a basic background check to get started. Once Postmates verifies your identity, they’ll send you a delivery bag and a prepaid card (in the mail) that you’ll use to purchase delivery items.
Now, unfortunately, there are a lot of scams when it comes to GPT sites. So it’s best to stick with well known, trusted sites that have been around for a while. You don’t want to complete offers for a month then when it’s time to cash out your earning find out that the site no longer exist. Trust me, I have seen a lot of “here today, gone tomorrow” rewards sites.
