If a book which you pre-ordered has not been sent and the displayed publication date has passed, this is likely for one of two reasons:

1 - The stock has not yet arrived at our distributor's warehouse.
2 - The publisher has changed the publication date but has not yet notified of us the revised date of publication.

In both instances, the availability status will display the following:

98% of pre-orders are fulfilled within 5 days of the publication date, however, there will be some instances where this is not the case. If this happens to an order you have made, it will likely be due to reason 2, listed above.

As soon as the publisher has provided a revised publication date, it will be displayed in place of the above status on both the product page and on your corresponding order page.
