Didn't receive your items?

Digital textbooks are delivered via email. Before contacting us check all spam and junk folders in your inbox as it may have been redirected.

Still don't have the digital textbook? Email customer support and we will look into it and resend if need be.

Hardcopy textbooks are shipped using outside delivery services and at times can incur delays beyond our control. A tracking number for the carrier will be provided so you can track where your textbook is.

If your textbook is lost in transit you will need to contact the delivery service to resolve the issue. If for some reason they report the textbook was never shipped contact us.
