Help!

I'm trying to order a copy of The Players and The Rebels from GGB.  In the past, I've sent them orders by post with a cheque.  This time, I thought I'd try and do it by Paypal.  But I can't work out at all how I'm supposed to do this.  On the website, the Paypal link just takes me to the Paypal homepage, with no order placed.  I know how much I'm supposed to pay but not to whom.

Has anyone done this who can walk me through it?  Or should I just get out the pen and paper again?
