I am wondering if it's possible to obtain product level data feeds that include more detailed information for our users than the typical affiliate provides.

For instance, if I have a category for Digital Cameras, camera XXX would display information such as Resolution, Zoom, Memory Card Type, Dimensions etc.

Is there any feed or service out there that could provide such in depth product information based on a UPC, MPN, or ISBN number? Or would I have to go to each individual manufacturer and ask them for a feed??

Thanks for any help!
