How do I change quantity?
After you've added an item to your cart, you may adjust the quantity on the 'Cart' screen. Simply use the drop down box next to your item to select the quantity you'd like. When you are done and ready to check out, tap 'Continue to Checkout' to complete your purchase.
During checkout, you may change the quantity of your order after you enter a recipient. Tap 'Add Recipient' on the checkout page, enter the name and address, and then tap 'Save'. After you save the recipient, you may tap the '+' and '-' buttons to the right of the recipient’s name to add or subtract books from your order.
