Start working exceptionally well for affiliates?

Last week it would appear that http://www.adamsreviews.com suddenly started generating a lot of sales for a lot of affiliates and i dont understand why all of a sudden, there was such a large increase in affiliate sales from the site.

Anyone have any ideas why this would be the case, did i miss some news about review sites in the last week that could explain why all these sales have been made from Adams Reviews or something?

Regards,

Lee
