EBay to me, is one of the easiest ways to get started when trying to make money online. You don't need to build a website to sell there, they host your images and listings. You don't need to drive traffic to your listings, eBay attracts millions of buyers each and every month. There's little to learn to get started. You can literally start making money within 24 hours.
So, what do you sell?
For the past 3 years I've earned my living from selling public domain material on eBay. The great thing about public domain material is that it can be sold as is without modifying or altering it.
Here's an example of a seller selling public domain material (his listing has generated $19,233.89)
24books Home Canning Self-Sufficiency Recipes Backwoods | eBay
The seller is selling 24 public domain ebooks on home canning. These ebooks can easily be found by searching on archive.org. Also if you notice, the listing does little selling and is very simple yet, it's generated close to $20,000 and 147,041 page views (see counter towards the bottom of the listing). Not bad for a 50 cent a month listing. This reinforces what was said earlier that ebay is one of the easiest ways to start making money.
Now if you browse through the seller's items you'll notice that this isn't the only item he sells. Most of the items he sells contain public domain material. Using Terapeak I was able to see just how much he makes from all of his listings, and they've generated over $9,000 in 30 days!
This is only one seller, there's a lot more sellers that sell PD material.
Here's a tip for finding more PD items that SELL. Most sellers include a notice stating that the item they are selling is in the public domain. To find these listings type "public domain" (cd, dvd) into ebay's search engine and check mark "include description" and hit search.
Most of the PD items that are sold on eBay can be found on archive.org or by searching on google.
