We (as in me and a team of amazing designers not we as in invisible corporate entity) just relaunched Yahoo! Shopping.
I'm pretty exciting. We've got the comprehensiveness of a froogle with the comparison power of a dealtime and we're working to reviews like amazon (we need more) including much-needed merchant reviews.
Plus I think it's got a simple crisp look, a slight updating of the classic Yahoo! style.
Search rocks, browse does a cool thing where we blend hierarchal classification into facets where appropriate (not unique, admittedly, amazon and a few others do it too)
And guess what? A sitemap on every page.
