How long until I get my preorder?
Please note that when purchasing a preorder book, it will only be dispatched after the release date stated on the description above.
Preorders within the Republic of Ireland are usually processed, dispatched and delivered within 2-3 working days of the book’s release date.*
Preorders going to Northern Ireland and Great Britain are usually processed, dispatched and delivered within 3-8 working days of the book’s release date.*
For timelines on international deliveries, please refer to our Shipping & Delivery Page.
*Please note that during peak trade times this timeline may increase.

Why can’t I buy a preorder with any other item?
We work to process orders as soon as they’re placed so that you get your delivery as quickly as possible in one go. 
Preorders are not immediately dispatched as they are delivered upon the respective release date. This means there will be a wait between placing your order and receiving your order.
If you need to add more items to your basket, we recommend placing a separate order for this. We will send out all the items in your order in one delivery and preorder items will always arrive just after their respective release date.

Can I cancel/amend my preorder once it’s placed?
If you’ve purchased a preorder title but noticed a mistake on your order, please contact our online team at customercare@bookstation.ie and we will try to fix this for you before the book is released and dispatched.
Once your order is shipped and physically in transit, we can no longer offer any amendments to your order.

How much is delivery?
We offer FREE delivery on all orders over €10 within the Republic of Ireland.
Delivery is just €3.95 for under under €10
Delivery starts from just €9 for orders to Northern Ireland and Great Britain
For international rates, please refer to our Shipping & Delivery Page.

Do you provide tracking for my order?
We provide a Tracking Reference for all orders placed online as standard.
Once your order is dispatched, you will receive an email with a custom An Post link to track your delivery every step of the way.

Can I cancel/amend my order once it’s placed?
Once your order is placed we work as quickly as possible to dispatch your order to you so we cannot promise this is always possible.
However, if you’ve made a mistake on your order and you’d like to change it, please contact our online team at customercare@bookstation.ie and we will try to fix this for you before your order is dispatched.
Once an order is shipped and in transit, we can no longer offer any amendments to your order.
