Instructions:A friend of mine gave this to me as I mentioned that I was ordering something from the site. Apparently she was sent this in a mailing to do with her Barclaycard. I don't know if it is meant to be for cardholders only but I have used it and it worked for me without owning a Barclaycard. I had my items delivered today and have been charged minus the discount. TIP - It would not let me use it more than once on my account but was able to use it again on OH's (different email address).
