17. Amazon – Have you heard of FBA? It stands for “Fulfilled by Amazon” and it’s getting pretty popular. Basically, you buy products (in bulk is best) and ship them to Amazon for them to store. When your products sell, Amazon packs them up, ships them out and sends you the money (after taking their cut). There are people making a full-time living from FBA, while others just do it for some extra money.
Not only will this multiply the money you’re bringing in in a serious way, but it protects you against any sudden changes in the market or in your business. Remember that old saying about putting all your eggs in one basket? A few hours a week committed to just one or two of the following opportunities will put you in a much stronger position to be financially safe and independent.
Do you see all of those articles, tutorials and guides all over the Internet? Somebody wrote every one of them! If you have decent writing ability (no, you don’t need a journalism degree!), and knowledge in a few specific topic areas, you can be one of those writers. It’s an opportunity to make money online and without ever leaving your home. It’s also the kind of venture that can start out as a small side business, but grow into a full-time career.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
If writing books interests you, an option you have is to self-publish eBooks and paperbacks with Kindle Direct Publishing, and reach millions of readers on Amazon. Publishing takes less than 5 minutes and your book appears on Kindle stores worldwide within 24-48 hours. One can earn up to 70 percent royalty on sales to customers in the US, Canada, UK, Germany, India, France, Italy, Spain, Japan, Brazil, Mexico, Australia, and so on. One can keep control of one's rights and set their own list prices and also make changes to one's books at any time. BooksFundr and Pblishing.com are two other places to get your book published and earn money.
With drop shipping, you’re effectively partnering with a manufacturer or wholesaler to sell their products. This way, you don’t pay upfront costs to buy inventory, aren’t sitting on unsold items taking up expensive warehouse space, and don’t have to deal with shipping the products yourself. You simply create your site, fill it with drop shippable products, and drive in customers, with almost everything else done for you.
They often expect you to commit to working a certain number of hours per week, which is generally part-time. They will pay you an hourly salary for that work, so it is really more of an at home job situation than it is in an entrepreneurial way to make money online. Still, if you want to get involved in political activity, and you have the time and motivation, this could be a way to monetize that passion.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
If you love to travel and find yourself randomly searching for airfare sales or browsing Lonely Planet, why not carve out a niche for yourself as a private travel agent? My friend, Mark Jackson did just that, making extra money online with his travel consulting side business. Start with word of mouth recommendations from friends who know they can count on you for the cheapest flights, and then move on and create a Facebook or LinkedIn group to invite people who want to stay on top of the latest deals. Eventually you could spin this into a full-time consultancy teaching people how to make their dream trip a reality.
28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
Many people fancy themselves as designers. If you have a unique idea for a new product then it may be time to get it designed. This can be a long process involving prototypes, discussions with factories, package design, and much more. However, the profits once the product is on the market could be substantial. And remember, with Amazon FBA, your products can all be stored and shipped by Amazon, giving you time to think up your next invention.
