Hmm... this gives me an idea for a browser plugin: For anything you buy on Amazon, it automatically adds an affiliate link for your favorite charity or organization in, giving them a tiny touch of revenue.
Perhaps the UK Inland Revenue could use this and affiliate links to get some money out of Amazon as they're not getting much out of them through actual taxes.
[Jupiter Broadcasting](http://www.jupiterbroadcasting.com/) already does this, their affiliate plugin automatically appends their referral on any of about a dozen sites they can, and that is their main source of revenue for their podcasts.
I would assume that Amazon has something against that kind of automatic referral in their TOS somewhere.
