ok I'm not sure I understand your question still so let me delve into it.
CJ has a ton of sponsors that allow you to add their products to your site. You can even use their datafeeds to automate the process. Every product has a description so to me that's "content"
IAN.com let's you use their content to build travel sites and so does lodging.com.
You can add info on cities, places to see, etc.
In fact almost all the affiliate programs Ive worked with give you at least SOME content to enhance the selling of their products.
Is this what you are talking about ? ?
