I'm a little surprised at the postage for two copies to the uk? 7.50E? almost twice the postage of one, is it really this high? "world zone rates" seems to suggest outside europe. just wondering, before I place order, as I had hopes ordering two in one order for me and a friend would have a bigger saving on postage! and I know postage from uk to anywhere in europe for the weight quoted is about half the price.
