Clickriver: Amazon lauches verticle PPC program.

beta.gifAmazon's own own PPC program, Clickriver.

Clickriver Ads is an advertising program (currently in beta) that allows businesses to place sponsored links on Amazon.com, next to search results and on product detail pages.

It's a closed beta at the moment. I've applied and if they let me in I'll post a review after I tinker with it.
