Amazon Refuses to Pay-to-Play in Google’s New Shopping Search

As Google shifts its Shopping search to a pay-for-play model, one key commerce company appears to be sitting on the sidelines: Amazon.com. As noted in a New York Times feature that ran last weekend, consumers who search on Google Shopping can find Kindles from a variety of stores via the listings, but Amazon isn't one of them. Google Shopping's omission of the most powerful e-commerce brand on the web raises the question of how successful the company's new model will be.
