Download Exclusive Content
If you are wanting to find content that isn't used by as many people then you might want to find a company that offers exclusive content. This doesn't mean you have exclusive use of the content, just that its not listed on any other mircostock sites. If content isn't exclusive then you might find it on other sites with different fees.
