We'd like to let you know about an important change we're making to the Product Search data feed requirements. As you know, you can help shoppers find your products by including high quality, frequently updated product information in the form of attributes. In order to provide shoppers with the most useful information, we'll be making the "condition" attribute required starting on June 30th, 2009.
In order to keep your feeds active past this date, please remember to include the "condition" attribute for all of your items if you're not already doing so. Please include one of three values to describe your product: new, used, or refurbished.
Also I have a broken sitemap link that needs to be redirected.

I would be happy to work with you to ensure your products continue to appear in google. I have worked with household name ecommerce sites before and have had to maintain and provide google feeds for them.
