What do you base that on? Have you purchased a site like that for that price range? Is that what you would pay for this site? I have purchased sites like that for $20 to $1200. This site looks like auto generated content from RSS, APIs or scraping and it doesn't look like a site that someone would return to over a better developed site like Amazon.
A site is only worth what someone is willing to pay for it. Its very hard to value a site not knowing what it is going to be used for, the true traffic etc.
