After careful consideration, we have decided to enter into a strategic partnership with PriceGrabber to power the Product Submit functionality of Yahoo! Shopping as of March 11, 2010. As a result of these changes, Yahoo! will no longer provide the Shopping Web Services API, including Shopping Results (the Yahoo! Shopping Syndication Services) to you as of March 11, 2010.
If you wish to continue to display syndicated shopping results for products listed on Yahoo! Shopping, you must apply to PriceGrabber for shopping syndication services. Although they do not offer a free web services API, you can find out more about how to apply to their program here: http://www.pricegrabber.com/about.php/about=corporate/sub_opt=10.
It has been our privilege to provide you with Yahoo!s shopping syndication product, and we hope to continue our relationship with you in other areas long into the future.
The Yahoo! Shopping Team
