You’d think someone would have come along who just scrapes Amazon’s listings, applies their own intelligent indexing heuristics, and spits out a new search/browse page that just links through to Amazon’s regular product pages. Like CamelCamelCamel, but for dimensions other than price.
I thought about trying to build something like this, but figured that I'd probably just get sued. Also I think matching listings to accurate product metadata would be practically impossible even if you had a good source for the metadata, and it still wouldn't fix issues like inventory commingling in the warehouse or bait and switch listings that reduce product quality over time.
AFAIK in the kakaku.com case, between kakaku.com and shopping sites are partner. Sites (including Amazon.co.jp) gets customers, kakaku.com gets affiliate fee. Why this model won't work in the US?
