There are many affiliate programs that allow you to represent many companies, but of all I have tried, LinkShare rates at the top.  You will be able to earn money by promoting products and services from such companies as: Overstock.com, AT&T, Buy.com, McAfee, Office Depot, Dell, Direct TV, Disney, Target, WalMart, and the list goes on and on.
     When a visitor from your website (or Email) clicks on a link and goes to a merchant's site, LinkShare keeps track of all of the transactions that the visitor makes. If that visitor buys something on the merchant's site, you get a commission. In some cases, affiliates are compensated even if the visitor doesn't buy anything, just for having driven traffic to the merchant's web site.
      Hundreds of text and banner links are available for easy use. You can even choose to use the provided Banner rotator.   If you are only going to join 1 or 2 money making programs, LinkShare would be a great choice.
