I have a storefront @ Amazon and while I was checking the results of my datafeed campaing, I noticed "sponsored ads" within my products pages. At first, I assumed there were Google ads but they are not, they are ads by Clickriver which is Amazon's own PPC. Still in beta and taking apps. I already fill in my info for a key. Does anybody have a key to ClickRiver or know anything else? Check it out at http://www.clickriver.com
