It’s easy to change your e-mail details. Just visit your account page and select the Edit my Profile link in the sidebar.

We don’t store a single billing or shipping address. Instead, we keep addresses associated with each order. We pull the last address forward into your new order.

If you need to change the address associated with an order, email support@pragprog.com with the order number and the new address. We will be happy to update it for you. Generally we can do this within 24 hours, during business hours.
