I am so fed up with websites that change my 'Delivery' or 'Billing' information to something else AFTER I've entered it CORRECTLY. I had to enter details 3-4 times to get both categories (in different countries) to be how they needed to be. I AM so sick of taking over an hour to order 2 books. These glitches have happened largely at at Used Book bookstores! What is it? Driving me mad! Next time, I'll pay full price and give my business to Waterstones!
