Why do you have to register for a free postage discount when you order over £5-00 worth of books. I think it should be automatically done at the point of paying. I've just ordered two books, only buying the second so as to qualify for the discount. and what happens??? I don't get the discount, i have been charged the full cost of postage. I will seriously think twice before ordering from Amazon in the future, its just not playing fair. It will be interesting to see if i get a reply from Amazon, but i'm not holding my breath.
