They do charge shipping at £0.99 per 100g (seems that's £1.98 per a standard HD-DVD) not the best for shipping but maybe still worth it for a few people.
For anyone looking for HD-DVDs there are still a few going at HMVhttp://hmv.com/hmvweb/specialOffers.do?ctx=280;-1;-1;-1;-1&code=08WYQ
Twelves Monkeys or Bourne Supremacy @ £2.99 each for example (free delivery)
