As I have said before, we are big fans of Marks and Spencer for clothes. Their products may not carry trendy labels but then neither do they come at designer label prices. Many people in Britain, from royalty down, rely on Marks for underwear if for nothing else.
On our trips to the UK, we usually make time to call in at Marks to top up on clothing and in between we have taken advantage of their delivery service to Spain which costs £7.50 per parcel.
Now it seems, they have seen a market for their products in Spain and have a website in Spanish. I haven’t explored the site fully but I expect they carry all the lines that are included on the English version. As a huge bonus, delivery is free if you order over 35 euros worth of goods (that is not hard!).
