I am looking for the same thing. We have our banners posted on several sites (i.e. MySpace) and I would like a way to change the linking code (i.e. <a href=bla bla bla...) to a promotional discount so when a user clicks the link they automatically get a percentage off. I can go back and turn off the "promotional discount" when I choose. Since I supply and host the banners I can edit the banner to no longer offer the discount when I turn off the discount.

Is this possible and what would the code be?

Thank you,
Ryan
