Hi Malcolm,
Thanks for the positive comments - it's fantastic to hear Booko is saving people money and making book buying easier. WRT the cart functionality, the goal is to find the cheapest shop for a group of books - this is useful because shipping calculations vary widely between the shops - some have free delivery when the price of all the books is above $50, while some have a base rate + per item calculations. Unfortunately, only 2 shops have a function allowing me to add multiple items to their cart - Amazon and the Nile. When you have multiple items in your cart, the best Booko can do for the other shops, is drop you at the front page. Amazon and the Nile should ask you to confirm that you'd like to add the books to your cart. For the other shops, it's probably better to open tabs in your browser for each book and manually add them to your cart. Not ideal, but I figured the ability to find the cheapest place to buy a collection of books is worth the manual process of adding each to the cart.

Thanks again for the great comments,
Dan
