If you live near a university, there are likely all sorts of research studies looking for participants. While I was an undergrad at Virginia Tech, I got paid $500 to participate in a 6-week dietary study. The study provided all my meals and paid me, but I had to eat a 5,000 calorie diet of 50% fat for 6 weeks, plus I had multiple muscle biopsies, urine/blood testing, etc.
If you have nothing of value to sell from home then retail arbitrage might be a better option for you. Many people partake in arbitrage to earn a little extra money, and for some it has even become their full-time job. Retail arbitrage is the buying of goods at a low price and then selling them on a different platform at a higher price. Sales in shops provide ideal opportunities to pick up products for next to nothing. These can then be sold on eBay or Amazon for higher amounts, making you a nice profit.

Did you know you can make money simply by owning a car? It's true, thanks to a company called Turo. Turo is a “car sharing marketplace.” Next time you're in a new city and need to rent a car–instead of using an airport car rental, you could use Turo and rent actual people's cars! (Similar to how Airbnb replaces hotels). Turo lets car owners earn money in three ways: local pickup (renting your car from your own driveway); delivering your car to local places; and also by leaving your car somewhere to be picked up (such as at the airport). Earn Money with Turo.


Great list! I’ve used Poshmark to sell clothes/accessories. You take up to 4 photos, add a description, and set a size, color, and brand. I’ve sold 3 items so far (two dresses and a pair of shoes) and it’s easy. The buyer can purchase at listing price or make you an offer, to which you can counter-offer. At all times, you can see what your profit will be from your listed price. Once the transaction is accepted, you are emailed a prepaid shipping label to print. You package your item up in a brown box and ship, and when the seller receives it your funds are released. You can cash out as a direct deposit to a bank account at any time or use the funds to shop. I’ve also purchased a pair of jeans on the site and they arrived as expected. For like-new and designer labels it’s a great way to clear your closet and make a little cash all at once.
If you’re willing to take on some risk and have the heart of a true hustler, you can make extra money online doing commission-only sales for startups and other businesses. While you won’t be getting a regular salary, with the right sales strategies and skills as an inside sales rep, you can make decent money for each sale you bring in. And because you’ll most likely be working with startups, if you can negotiate a little equity you could profit big time if you're pitching a solid product and the startup succeeds.

My next self-funded business hit $160,000 in revenue in its first year alone. After that first taste of self-made success, I’ve gone on to sign consulting contracts worth tens of thousands of dollars with startups like LinkedIn and Google, launch profitable online courses, and build a following of hundreds of thousands for this blog and my podcast series.
I’ve done mystery shopping for about 10 years now. I started with Shadow Shopper…what a joke. I quickly learned…never pay anyone to get jobs. There are plenty of legit companies willing to pay YOU! I’ve been with Confero from the beginning and pretty much do one store for them, with over 100 locations in my area. I’ve made over $200 in a month, but most times around $50. I also belong to A Closer Look, ALTA360, Bestmark, Intellishop and Market Force. A Closer Look has very few shops, but they pay more, like $40 for a flooring shop. Do your research and you’ll be fine.
When creating a membership site, always offer different plans and pricing tiers to appeal to your different categories of audience. Access to specific types of content is then dependent on the plan selected by a member. Membership fees can be a one-off payment or a repeat subscription. And you can even sell products on your membership site to boost your income.
Sell plasma. After passing an initial screening, you can usually sell your plasma for anywhere from $25 to $50 per donation. To qualify, you’ll have to stand in a long line or show up early, be willing to fill out a very personal questionnaire, and endure a painful needle prick or two. Still, selling plasma is a great way to raise money fast – if you can stand the hassle.
I love the idea and that they make it so easy because the retail world is due for this type of disruption. This doesn’t happen as much with jeans and other daily wear items but those things you wear less than half a dozen times, like more formal dresses or accessories, just collect dust. You might as well recapture some of the value by selling it. Thanks for sharing your experience!

If you have specific writing/journalism skills or are adept in various IT/software domains, freelancing may prove to be a lucrative source of secondary income. Increasingly, companies are implementing a content marketing strategy and turning to outside sources for specific assignments, and if you can prove your worth there will be more work available. Even simple skills like data entry may be to your liking, provide you can offer at least 5-10 hours weekly.
Robert said he did an average of 4-6 of these gigs per year for a while depending on his schedule and the work involved. The best part is, he charged a flat rate that usually worked out to around $100 per hour. And remember, this was pay he was earning to advise people on the best ways to use social media tools like Facebook and Pinterest to grow their brands.
