Comparison shopping engines are channels for collecting product information, including pricing, from participating retailers and then display that collective information on a single results page in response to a shopper's search query. In this way, shoppers can compare prices, shipping options, and serviceĀ from multiple retailers on a single page and choose the merchant that offers the best overall value.
In 2013, Amazon secured a US$600 million contract with the CIA, which poses a potential conflict of interest involving the Bezos-owned The Washington Post and his newspaper's coverage of the CIA.[200] Kate Martin, director of the Center for National Security Studies, said, "It's a serious potential conflict of interest for a major newspaper like The Washington Post to have a contractual relationship with the government and the most secret part of the government."[201] This was later followed by a US$10 billion contract with the Department of Defence.[155]

Before picking up this excellent book, I was wary of online shopping -- and I still am, but now I'm intelligently wary. The authors do a marvelous job of helping understand what you can trust and what you can't, how online shopping works in all its various manifestations, and what strategies to use when you do shop online. The book showed me that online shopping is not (as I had thought) just for shopping addicts who need a fix 24 hours a day, but a great space for intelligent and discerning consumers. I'm still not a big spender online (or anywhere), but I've used the book to help me find some things I couldn't find anywhere else and at surprising prices. I think this book is going to go down in the so-far brief history of online commerce as a milestone achievement. It has certainly changed my views about WWW commerce and made me a better consumer. I can't say enough about this expansive, easy-to-use, fun, and informative work. I hope they plan to update this work regularly.
