Can I purchase multiple books in one order?

Yes, of course!

When you've finished configuring your first book of choice, follow the instructions until you get to your shopping cart. In your cart you will see the book you've just created. Beneath this is a button saying '+ Add another book', if you click on that, it will take you back to the products page where you can then create another book. You can repeat this step as many times as you like. Both books will be shipped in the same parcel to the shipping address of your choice. 

Have fun creating!
