If you already have a website or blog, look for vendors that offer related but noncompeting products and see if they have an affiliate program. Stick to familiar products and brands—they're easier to sell. For promotion, place simple text or graphics-based ads in appropriate places on your site; you can review or recommend products or create a dedicated sales page or website to promote a particular product.
What a huge, great list of ideas – bookmarked this as I know I’ll be coming back to go over it again and again. Here’s another item that could have made the list. I found a financial directory that’s useful for info on making money online. It’s http://money.madbeetech.com. What I like about it is that each directory listing includes ebooks and videos that can be instantly downloaded. All sorts of stuff for people who have their own website, and people who don’t (but still want to make money online).

While for decades, this has all been done in person, there is a budding crop of sites that allow notaries to take their services online. If you’re already a notary, you can sell your services online. Or, if you want to get started, check out the National Notary’s checklist for becoming a certified notary.
Competition is stiff, but if you are a savvy designer, this is a good way to pick up extra dollars. Even better, if you are an artist, this is a good way to make your art skills pay off. Consider that every design will need to have a reason why the customer should buy the book or follow that person on Twitter to have a real impact. Twitter backgrounds, in particular, are in hot demand right now. For measurements and caveats of Twitter backgrounds, read “How to create your own Twitter background.”
Over the past seven years, I’ve helped sell over 50 different types of products online by providing marketing services. I’ve marketed and sold so many things for people online, including master’s degrees for universities, headphones, travel experiences, hats, sports memorabilia, prefabricated homes, insurance, legal services, real estate services, dental services, and even supplements. In all of these cases, I was getting paid by someone else to sell their products online – none of these were my websites or my products.
