Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
I personally like this one for some spare cash. It does not take much to earn an extra $20 – $50 a week. Some claim that they are able to make a living by dedicating their time to different jobs at mTurk. You will have to go through a learning curve, but once you get comfortable, you will find plenty of good and interesting HITs (Human Intelligence Tasks) to work on.
So, I started reading and learning about affiliate marketing and blogging. I combined the two and after a 14-15 months of really hard work (sitting in front of computer for 14-6 hours a day and putting things I had learned, into action (building a blog, writing articles, promoting the site, etc), I started making enough money that I started believing in myself and the idea that I too could make a full time income online. From then on, I just kept on going and the income grew and grew. Now, I still work 8-10 a day on my online business, and sometimes even more. You have to constantly work and maintain it. Most people think because its online, its easy. That’s where they get it wrong.

I think you can do well with this business if you start with people in your neighborhood and ask them if you can have an opportunity to perform this service for them. Word of mouth will travel fast if you provide a good value. I think the key to doing very well here is to package your service. For example, try to find a price that works for mowing, weeding and fertilizing altogether.
While some might think that starting a blog is an arduous effort, when you understand the precise steps you need to take, it becomes far easier. It all starts in the decision of choosing a profitable niche and picking the right domain name. From there, you need to build your offers. You can easily sell things like mini-email courses, trainings and ebooks.
great information. i recently used your “Start an Online Store” suggestion, but quick turned it from junk in my garage to small business. i found a way to make some quick doe. i found these, “8 point and 7/16 wrench catv cable star key security tool” listed on eBay for $50.00 each. Found the source (newelectronx) that sells them for $5 to 15 bucks per piece. I sell them on craigslist for a good return. i’ve been making good money every since. i’m not wealthy yet, but income is going smoothly and sell aren’t that bad. profit is at least $35 per sale. if i sell eight pieces per day then i make like $280 which is better than a 8 hour job to me. so online selling works.. try it
Webinars are quite possibly one of the most potent ways you can make an exorbitant amount of money online. You'll need an audience to train and you'll need to know what you're talking about. Of course, this usually requires having a website and some semblance of an online presence. However, people can still do webinars without all of that. For example, you might have a sizable social media following and you train them every week on something to do with social media. But you will need a product to embed and sell at some point. Don't worry about it in the beginning. In my experience, the best webinar platform out there is GoToWebinar. 
This is slightly different than eBay Arbitrage. Find a distributor that will sell to you at their discounted prices. List these items online. Buy and ship to your heart’s content. Basically, you become a reseller of computers and other hardware. Another thought here is to sell computer parts. Can you find a part that seems to be in demand? If you can supply the demand, you may just have yourself a part-time business.
You can potentially make even more money by offering to handle snow removal in the winter. Shoveling snow is often a homeowner’s least favorite job, and there are many homeowners who simply cannot handle their own shoveling because of physical limitations. Typically, snow removal companies charge a flat fee for the winter, no matter how many times it snows. You can offer to remove snow a la carte, or you can copy the standard procedure and charge a flat rate. If you already own a snowblower (or can invest in one), this can help you speed up the snow removal process and allow you to take care of multiple neighbors each time it snows. (A snowblower will also save your back muscles!)
