Are there any coupon codes or discounts available that I can apply to my purchase?

The discounts we offer are only for certain courses and schools. Your instructor for your course will let you know ahead of time if there is a discount code you can use for your purchase.

I’m not sure what book I need to buy

Check the ISBN number. It will be a 13 digit number beginning with 978. On the item page in our store, that be found on the right side. That will identify the correct book better than anything else. If you don’t have one, check with your instructor or check the course syllabus.

What is an ISBN Number? Where can I find it?

An ISBN Number is 13-digit number which typically begins with 978 or 979. It is used as the best method for identifying a book. When working with you regarding one of our items, we often ask for an ISBN number because many of our items have similar titles and we want to be sure we’re getting you the information for the correct item. The ISBN number is most often located near the barcode or on the inside cover of a book

I’m purchasing a book for a course, and I don’t have an ISBN number. How can I be sure I’m purchasing the right book?

The title of the book can be a good way to tell but isn’t always reliable. The book’s edition number and author also can be good to check. The best way to ensure you’re purchasing the correct item is to check with your instructor and ask for an ISBN number. If you get in touch with our support team we can offer suggestions for what we think it is based on the information you provide. However, without an ISBN number we aren’t able to ask you to purchase something that might not be right.

The store page has a print version and an eBook version, but the ISBN my instructor gave only matches one of the versions. Is the other still okay to buy?

Yes. Different versions of an item need to have different ISBN numbers but typically the only difference is the format. The content will be the same.
