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.
3. Mturk.com is a service that has been around since 2011 although not many people know about it. You can signup and be paid per task. A task may ask you to copy down phone numbers from a web search or it may ask you to filter images. Each task pays differently and you are rated on your accuracy. If you are quick & accurate then you can earn quite a bit. There are plenty of jobs to go around and you can work as much or as little as you want.
1Additional activation for cash back is required. Transactions eligible for 1% cash back include: credit transactions which you sign for and which are processed via Mastercard; online transactions processed via Mastercard; and phone transactions processed via Mastercard. Transactions that are not eligible for cash back include, but are not limited to: purchases processed via a debit network (including PIN-less debit transactions); cash withdrawals and cash advances. Additionally, you'll only receive cash back when your monthly earned cash back is at least $1.00 USD. Cash back earned that's less than $1.00 USD will not be awarded and does not carry over to the next month. See the Cardholder Agreement for complete details.
After you sign up for an account, you can start receiving money right away. To use the funds in your account, you can transfer them to your bank account (you will need to add one first). A bank transfer usually takes about 1 to 5 business days. Or, you can request a PayPal Debit Card and have your funds available to use right away. PayPal Debit Cards can be used almost anywhere just like a normal debit card from your bank.
