but ecommerce isn't a newspaper. not even close. newspapers include content which is informative or interesting for readers. ecommerce sites sell products.
if i have a product page for large aluminum green fuzzy widgets, and another for large aluminum green smooth widgets, they are likely to share lots of dup info. - like the manufacturer name and the dimensions and a description of the use etc. - the different content is likely to be only the product id, upc, price and info about the texture (smooth vs fuzzy).
on my sites, user data has proved time and again that dup content - at least as described above - is good. customers want to see all of the info about a product and a manufacturer on the product page - lots of this will dup - its ok because they don't browse that way and the info is highly relevant to their purchase.
thankfully google gets this - yes, there are dup content filters, but i think they are trumped by user data. if your users like your site, google will like your site - more and more i think that is where search and seo are headed.
