I'd like to add another book to an order I just placed. How do I do this?

That's great to hear! 

If you'd like to place a second order  within 10 hours of placing your original one, you can do this directly via your confirmation page. This way your orders can be sent together and it'll save on shipping costs. If you're shipping to a separate address however, it's best to create two separate orders. Any questions, please don't hesitate to get in touch with us.
