Hi, Mollie,
Well, I just checked back to see what I actually paid for it a couple of years back and it was just shy of £55 - I bought it from the States and the postage cost was almost as much as the game itself!! Ideally, I would obviously like to recover what it cost me so something around that figure would suffice.
I am based in the UK, in the lovely city of Edinburgh! If you're interested, please let me know.
Cheers.
Jim
