We launched our affiliate program 9 months ago and as it grows our affiliate to in house ratio is narrowing every month. Right now it is at 70% in house 30% affiliate, the way things are headed i think it will be around 50/50 within the next 8 to 12 months. One of the reasons is, things like catalogs, flyers, print ads, model appearances, sponsorships etc do not have the same impact that they had 3 or 4 years ago, i think most people now are hearing about your site via the internet with things like tgp's review sites, banner links, and blogs this is where all the large amounts of traffic are comming from.
