There are basically two ways to get a product that you can sell online.  They are:

• Sell other people's programmes/products on commission or as an affiliate;
• Create your own product or service and sell that.  This is the nirvana of internet marketing and should at least be your ultimate goal, as it means that you will be able to keep all of the cash from whatever you sell. 

If you are wondering what the difference is between selling on commission and selling as an affilliate, it is this: selling on commission isn't available everywhere but, where it is, there is usually no need actually to purchase the product yourself - you just get other people to the seller's website and hope that his/her sales-letter can do the rest.  This usually makes it much cheaper for the marketer to set themselves up.  However, many product owners do not like this for two reasons:

• Those selling books are usually convinced that the contents, and your enthusiasm for them, will help you to clinch your sales.  This is especially true for books on internet marketing, whose authors generally believe that the advice contained in the product can help to sell it and should therefore be followed, which is logical anyway - it is hard to sell a book saying do things this way if you are marketing that very product by doing things another way!
• Genuine marketers believe (as do I) that it is easier to sell something that you can honestly tell your prospects you use and get some benefit from.  If this is the case then you will be more convincing, and therefore more persuasive, when you speak or write to your prospective clients.

Whatever the relative benefits to the marketer are, opportunities to sell as an affiliate are usually easier to find and come with a host of advantages, free facilities and, frequently, access to free advice.

The final distinction that needs to be clarified is the difference between selling a product and a programme.  A product is something tangible, such as e-books, CDs, health-foods, cleaning products etc. whereas a programme is generally service-based.  The advantages of each are that products are probably easier to sell; even someone who is not a car mechanic may be interested to know about this fascinating trade and may, therefore, buy a book on the subject, and who isn't interested in getting great deals on lots of items (for an answer to this question, see e-bay's membership stats!).  On the other hand programmes, because they are service-based, rely on people being in a position to use the service - a programme generating website-traffic will be of little use to anyone who doesn't own a website (which is about 99.95% of surfers!).  However, selling a product usually generates a single, one-off payment, whereas a service will usually generate 'residual income' because they are subscription based.  This means that, if you get someone to subscribe to the programme, you get a part of their subscription every month.  So, these people are harder to find, but they generate income for you for as long as they continue to subscribe to the programme.

Anyway, here are the biggest and best opportunities I have found on my tours around the internet.  You will also note that much of what is here is based around internet marketing, advertising and traffic-generation.  That's because these are the big business opportunities at the moment and these are therefore the items that are selling the most easily.
