PointsPrizes delivered a working Steam wallet code in exchange for 3,000 points that I accumulated over several weeks. Though it took slightly more than a week to process my claim, the important thing is that they kept the promise, so the site is legit. I had a few problems with some external survey sites that kicked me out just before completing a survey after investing like 15 to 20 minutes (happened twice) and about 2 or 3 others that somehow failed to credit despite the survey being completed. But most of the time, it gets properly credited, and eventually you can reach the target if you are persistent enough despite constant survey rejections. The only thing you have to decide is whether you are prepared to invest the amount of time needed (if you rely on surveys).
Inbox Pays, at least for me, doesn’t seem to be worth the time. The cash out threshold is high at $50, and you have to do more than just read emails to get paid. You have to also complete offers. According to PTC Investigation (I site I generally trust for reviews of sites like Inbox Pays), you also have to talk to them on the phone in order to verify your account and get paid.

InstaGC is a rewards site you can use to redeem instantly for Amazon gift codes (and all kinds of other gift codes). With this site, it's possible to earn money for doing all sorts of things which include short tasks, surveys, watching videos, listening to music, and more. What I love most about this one is that when you do redeem, there is NO waiting. You just ask for your code and it's there waiting for you on the next screen. It's also possible to request a check for a cash payment, but you will have to wait several days for that to show up in the mail.
Fiverr is a popular platform for offering services. You can create your own Gigs to have available for sale. As the name suggests, Gigs are available to purchase starting at $5 though you can offer upsells to increase your earnings. You do need to wait 14 days between completing a Gig to being able to withdraw your earnings by PayPal. There are fees associated with these transactions.
