Microsoft released a refreshed Bing Shopping section.
"One of the updates is a left-side navigation improvement which adds more filters for narrowing down your choices, based on the item you're searching. In the example, it only took a few clicks to narrow down 38,000+ laptops to 3. There's also a new information on product descriptions, product reviews ratings, product summary pages have been updated too, to include more product images from the merchant's site, free shipping information, detailed ratings and reviews."
The latter comes from ResellerRatings.com, a site which includes more than 430,000 consumer reviews of online retailers like Newegg, TigerDirect, DiamondShark, Buy.com, and B&H.
