I am finding multiple sellers (ebay.com) of these two disc Full Screen releases - still at reasonable prices - but they will only ship to the US and will not even accept messages to ask if they would help me out with UK postage rates!!
Very frustrating but I am still hunting around........
EDIT. I finally found a seller willing to mail to the UK so I have now won ANH. Just ESB and ROTJ to go
EDIT EDIT. ESB now on the way. Just ROTJ to go now.
