Redemption Codes are your means for obtaining CourseSmart eTextbooks when you haven't gone through the purchase process on the CourseSmart web site.
When you purchase a CourseSmart eTextbook rental through one of CourseSmart’s partners or through your campus bookstore, you receive a Redemption Code. You may also be given a CourseSmart Redemption Code by your school, as part of your course registration. This code is redeemed on the CourseSmart web site for immediate access to a specific eTextbook.
An eTextbook obtained via a Redemption Code is identical to one purchased on the CourseSmart web site--same rental term and same functionality. It joins your other rentals on your CourseSmart bookshelf.
