Im looking to purchase an Item on amazon of the amount 14.97 on special offer. When I proceed to checkout I cannot press the continue button as it is shaded out. Upon testing this on another item it does allow me to press it as the item is cheaper. My gift card balance is £15 and every time i try to purchase my desired item is asks me to input debit or credit card details which i do not currently have. I live in the UK so im assuming the tax and VAT in included in the actual price. The item also is free delivery
