Appendage to my first ever second post

My brother received the following recommendation from Amazon:

Amazon recommends "Punk: The Definitive Record of a Revolution" by Stephen Cosgrave
We recommend the items above because you purchased or rated: Barrys Irish Gold Blend tea bags 80ct

Firstly, yes my brother did buy tea bags from Amazon. Apparently 5 minutes is too long to have to walk to Tesco ;-)

But seriously, Amazon needs to fix the algorithm that finds relations between these items. Or at least the metadata they're using to describe them. If you yourself, dear reader, have received such emails, do let me know.

My first ever second post

Every now and then I get these emails from Amazon, as I'm sure most people do, which recommend things for me to buy based on my previous purchases. Today I received one such email recommending 2 items.

1) Seinfeld Season 8 DVD boxset
Why? "...because you purchased or rated: Seinfeld Seasons 1-3 [1993], Seinfeld Season 4, Seinfeld Season 5, Seinfeld Season 6, Seinfeld Series 7"

Fair enough, the second item...

2) "The God Delusion" (book) by Richard Dawkins, described in one review as "...an acerbic polemic that argues that the Abrahamic religion, from which Christianity, Judaism and Islam are off-springs, are essentially at odds with and diametrically opposed to modern, educated, scientifically aware societies."
Why? "...because you purchased or rated: Philips SBC HP820 Headphones"

Am I missing something??
