My friend Graeme has very kindly put together a little firefox greasemonkey script which I use to switch between the same book on amazon.com and amazon.co.uk. It's really handy because I often look at the reviews on amazon.com but then buy on amazon.co.uk. I find it incredibly useful.
Graeme hasn't yet packaged up the script for universal use ... but if he did, would you send me an email if you'd find it useful?
