UK shopping in Spain

I happened to notice the other day that now it is possible to buy from several large UK stores online and get courier delivery to your Spanish address, Argos-Spain have around 8000 products, any amount delivered for 9.95 euros, Next, has a delivery charge of 5 euros, John Lewis delivery charge 7.50euros  Theres also Marks and Spencers with international shopping. There is also the "UK shopping in Spain" company based in Mazarron where you can order from over a dozen different UK stores and they will deliver the whole order to you, you pay for delivery by weight and this one seems to work out quite expensive in my opinion.
 To buy a new laptop or PC from Marks and Spencers or Argos could be ideal as the operating systems are English where as it is not easy to get an English version on a laptop from a Spanish store.
