I have, as a gift voucher, £21.11 as my balance. I haven't put any credit card details because I'm 14. Before hand, I could buy books, but now, even though I still have money left, it says: "you do not have a valid default credit card specified for your amazon.co.uk account" Why does it do this? How can I turn it back so I can carry on buying stuff with gift cards?
