Okay, this wasn't working for me in 3.7.4 PL1, and now I've gone to 3.8.0 -- do I have any hope of getting it to work in that version?
Also, I have one further question about the hack on the last page to get it to work with Amazon.co.uk, what exactly do you mean by 'add the bit in the preg_match to work with this'? I'd like to give it one last go before I throw my hands up on this entirely.
