The cheapest e-Books are free; at least that is what people want you to think. The truth is that most free e-Books have been widely distributed, and thus do not help you master your market niche completely enough to make a ton of money. This doesn't mean that free e-Books won't make you money, or be a nice compliment to your sales library; it just means that they aren't the best e-Books to stock. If an e-Book is free there are a number of reasons why it is free, understanding these reasons can help you find valuable low cost e-Books in the end. The free e-Book is usually given away in trade for an email address that can be added to an affiliate list. This is called an opt-in email list that will be used to send you product offers in the future. If a free e-Book is available without having to add your email address, chances are they want to advertise the products, or services in the e-Book to you. This means that the contents of the e-Book while somewhat valuable will be tainted by the blatant advertising. This means that when you are trying to resell said e-Books on eBay, they won't command that high price you so desperately need them to, instead they will sell for pennies.

E-Books worth the much money are those that are exclusive, or hard to find e-Books full of information that can truly benefit the readers. These e-Books are either self written, freelance written, or purchased in limited numbers for a copyright holder. Finding these e-Books is a lot easier then you think. All you need to do is decipher what program online will offer you the most amount of exclusive, or limited issue e-Books at the lowest cost.

You can sign up for monthly memberships to content supplier clubs, or you can pay per document online. Typically to buy a niche e-Book with resale rights might cost you between $50 and $300 or so. That being said, you can charge $49 on eBay, and sell 10 copies a day for a year straight. The numbers can be outstanding, and worthwhile if you know what the public is looking for.

Another way to locate the highest demand e-Books is to have them done from scratch. First figure out a hot topic, next hire a writer, third brand the e-Book so it won't be stolen, and sold without your permission. Having a small e-Book done, can greatly enhance your credibility as a vendor on eBay. Can you imagine putting the words, "only available through me" on your listing? This would help sales fly in, and keep your e-Book business profitable online for many years to come.
