It does not seem that they have an English version on the El Corte Inglés website, no. But it does seem they allow people from outside of Spain to make purchases. You have to register first to make purchases (of course), and they require your passporte or DNI number. Once you have chosen your items and put them in the shopping cart, you can either register yourself or NOT register in order to make your purchases. If you register, that page has an ENGLISH version clickable link but if you don't register, that page is only in Spanish.

In order to be sure you're not making a mistake or misunderstanding something with your order I would ask one of your friends to "oversee" the purchase for/with you.

I don't know of any other website in Spain for shoppers but no doubt there are hundreds or thousands of them. You could probably see many of these advertised @ http://www.Terra.es .

Good luck and happy holidays! Saludos, MadridMan
