Whoever wrote this, did things right by keeping things simple(compared to Amazon's own window shopping application and many others). What amazed me was that the author doesn't appear to have put on affiliate links in those searches (or maybe Amazon tracks the referrals in some other way?).
I can't tell if the affiliate link is hidden or not. Traditionally Amazon affiliate usernames are "username-20" and as you can see in the URL the pattern does exist, only with a strange username: "_0"
That's quite impressive. I think my favorite simple feature: it doesn't try to build its own search engine. As a result, I could find some of the really hard-to-find items on Amazon, which I doubt a more custom search enging would have done.
I think that's really smart. There isn't much point building your own search engine now unless you are very large. There are normally a few great alternatives with some kind of partnership arrangement out there to use instead.
