I placed a book in my cart then went to checkout to pay for it. When logging in, I found that I needed to change my password first. I got my password changed successfully but in the process, the screen containing my cart with the book I wanted to buy had disappeared. I had to wait 12 hours for the book in the cart to be released and made available for me to place in a new cart for me to finally buy it. Not a good shopping experience! I think it would be good if you could fix this glitch on your website.
