If your order arrives and something's missing or not quite right, we've got you covered. Please report any shortages or errors to our Customer Service Team within 30 days of your expected delivery date.

A few things to check first:

* Multiple packages: Some larger orders may ship in multiple packages, each with its own tracking number. Check your shipping confirmation email(s) to see if there are additional shipments on the way. Account holders: You can also check your My Orders.

* Short-shipped items: Occasionally, a book may be short-shipped. Because we sell publisher overstock, our inventory moves fast and in rare cases, a title that was in stock when you ordered may become unavailable before your order is packed. If that happens, you won't be charged for the missing book. Your pre-authorized payment will be automatically adjusted to reflect only the items that shipped.

Want to know when it's back? If you have an account, add the short-shipped title to your Wishlist and we'll email you when it comes back in stock – just make sure you're subscribed to Wishlist notifications in your email preferences.
