Gazelle. If you have an old cellphone or an Apple device, you can sell it here. The website will give you a cash offer for your device. If you agree, you'll be sent packaging materials. Gazelle pays the shipping costs, and you wait for a check in the mail, a gift card to be sent or cash transferred to your PayPal account. You may not make a fortune, but it's better than letting an unused device collect dust on a shelf – and far better for the environment to sell it than toss it in a landfill.
Cafe Press: This website allows you to create digital designs that can then be sold on the platform. You'll earn a commission for everything that sells and you'll never have to deal with printing, warehousing, customer service and so on. The site has over 2 million independent designers that have created products being sold online here. If you have some graphic design skills, then this is a great potential source for your web-based income.
Earn cash back for shopping. Earning cash back on your purchases is a smart idea, and credit card rewards aren’t the only good cash-back strategy out there. With sites like ShopAtHome.com, eBates.com, and TopCashBack.com, you can earn up to 10% cash back on purchases made with approved merchants. Many frequent shoppers also love the Ibotta app, which lets you earn cash-back on every purchase.
I stopped using this method once I started my own card game site (more on this below), however I still believe niche collectables, particularly in a market that you really love, is a fantastic starting point to gain experience making money online. Like eBay you can make money selling secondhand items in community sites if you can find a way to source product at cost or below. It’s not a model that has much margin so again the challenge is to scale if you want to make significant profit.
Wonder. People come to this site when they need research done. Wonder doesn't just hire anyone, but you can apply, and if they think you have the skills to do research, you'll get access to their dashboard. You can then choose to answer a question – perhaps coming from a business executive or an author writing a book. Researchers report making, on average, $8 to $16 for each detailed answer, although you can make more, so this is probably only a gig for those who really enjoy doing some digging to find an answer, as opposed to someone who just wants to make fast money.
But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
