If you need to keep your rented book longer, we provide 15 day, 30 day, or 150 day extensions. To extend your rental, log into your Bookbyte account, locate the rental order, select the "Extend My Rental" button, and the extension options will open in a new window. If you would like to charge the extension to a different credit card than the original transaction, please contact us via email or submit a ticket through our Portal.
