Just a heads-up to let you know that in addition to UPCs and product keywords you can now also use our the UPCZilla engine to search for Amazon ASINs. Just type a valid ASIN in the search field at the top of the page and the engine should return the details of that product as well as its corresponding UPC, if available. Not really sure why someone would find this useful, but it was kind of a side-effect of using Amazon’s product search API so what the hey!
