I wonder if you could scrape some of these price matching sites, or even integrate with them. That way you could get a lot of product names and run a whitelist of products in stead of relying on people adding 100% correct and unique names. Would love to see common failure modes before deciding to buy something. Of course this could become an attack vector for the competitors.
