Specifically, this subreddit has a great, stickied list of sites and services you can use to make a little extra cash. I recommend reading through it in its entirety and thinking about what makes the most sense from a time/reward standpoint—as well as your personal preferences. You might actually enjoy filling out a ton of surveys, say, over dealing with researching and finding new Mechanical Turk projects to complete.
Yet another Amazon service providing the possibility to make money online is the Audiobook Creation Exchange. You can create a standalone audiobook, or create an audio version of your eBook as complementary media. And you can narrate your audiobook yourself, or Amazon can put you in contact with a professional to help. Once sold, you can then earn up to 40% royalties per audiobook.
Open an Etsy store. If you have a creative talent or skill – whether it’s creating art, sewing clothes, or making keepsakes – you can open an online store on Etsy.com and sell your wares for some quick cash. With your own Etsy store, you’re left in charge of pricing and, ultimately, how much you make. See our detailed primer, “How to Make Money on Etsy.”
3. Invite your friends to Neobux - After being a Neobux member for 15 days and clicking at least 100 ads, you can have direct referrals through a referral link. You can get your referral link clicking "banners". Send your friends the link via email, facebook, etc. When someone joins Neobux using your link, they become your Direct Referral and you will get commissions when they click ads.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
