smarter.com seems to be a popular shopping comparison site, but do any of you know if it is related to shopzilla/bizrate?
I was actually just about to post and ask the same question. I've finally got all my products into google products last night and was on the look for other product search sites. The only ones I've been able to find so far want to charge per click, and on top of that a fairly high cost per click. So the real question is Are their any product feed sites that do not charge per click that have any decent traffic?
Good question. Once they become popular they seem to begin charging. I think Google could head in that direction, if and when Google Base becomes popular.
