We're travelling from Australia and have the option to also buy from Raileurope - check their website as for us it works out cheaper than buying from the swiss travel site. www.raileurope.com.au At the top of the page you can change countries, not sure if it works for UK but worth a try if it saves money. Also gives you details of options for different passes.
We're going to be there from 22nd to 25th May, not booked the pass yet, keep me posted how you go!
