Apparently you can call 0044 151 4821292 from abroad to place an order. I think you get through to a Customer Services person rather than the orderline or QCut but they will be able to place it for you.
Freephone (0800) numbers won't even connect from abroad, as you cannot add the dialling code for the UK.
Obviously, a phone call will cost, especially from a mobile - but at least it's a failsafe option if you've no internet or 3G access. I guess it will be a fairly quick call too. :grin:
EDIT: Just checked my mobile contract tariff - calls made from EU are 38p per min. Mobile internet is £4 per hour if you buy a 'pass' in advance, otherwise £5 per megabyte (approx viewing of 10 webpages).
