The Amazon Shopping App that was featured at International CES 2011 is now available in the Windows Phone Marketplace!
Swiping left or right to slide between product details, reviews, related items, etc. is a much better experience than the limited Amazon mobile website. The application also provides the ease of access to 1-click ordering, Wish Lists, package tracking, reviews and related items.
The app is available for free, and is a great companion for outdoor shopping trips as well to check reviews of products you intend to buy at a store.
