I was speaking to somebody from IRHH yesterday and I am sure that you will be getting your copies soon, they did say that they had received a lot of requests for this puzzle. I can give you the phone number if you want.
As far as postage is concerned an A5 envelope and normal postage is ok though their are a lot of questions it is a compact booklet.
