The Textbook Savings Checklist: What to Do Before You Buy

Start here: the things to check before spending money on textbooks

Before you buy or rent a textbook, there are five concrete things to verify. Most students skip at least one and end up spending more than necessary or buying the wrong edition. This checklist walks you through each one in the order that saves you the most money.

The goal is simple: confirm what you actually need, find the cheapest legal source for it, and make sure you can return it if plans change. Most of this takes less than ten minutes per class.

Key Takeaways

• Check your syllabus and email your professor before buying anything — some textbooks are optional, and some professors provide free copies or alternatives.
• Verify the exact ISBN or edition number your course requires, because buying the wrong version means you cannot resell it and may not match homework problems.
• Compare prices across your campus bookstore, Amazon, Chegg, VitalSource, and used marketplaces — the same book often costs $50 to $200 more at one place than another.
• Check your school's textbook rental program and your library's course reserves before you commit to buying — both are often free or very low cost.
• Read the return policy before you complete the purchase, because some sellers have strict windows and some do not accept returns on digital books at all.

Step 1: Confirm the textbook is actually required

Start with your syllabus. Look for a section called "Required Materials," "Textbooks," or "Course Materials." If the syllabus does not list a textbook, send your professor an email asking whether one is required for the course. Many professors list textbooks as optional or recommend them without requiring purchase.

If the syllabus says "required," ask your professor directly whether you can use an older edition, borrow a copy from the library, or use an open-source alternative. Some professors are flexible about this and will tell you so. Others have specific reasons for the edition they chose — usually because homework problems or page numbers changed — and will explain that too. Either way, you get a straight answer instead of guessing.

Check your school's library website for the textbook title. Many libraries keep textbooks on course reserves, which means you can borrow them for a few hours at a time during the semester. This does not work if you need the book constantly, but it can work if you only need it for occasional reference or if you can share access with classmates.

Step 2: Get the exact ISBN and edition number

The ISBN (International Standard Book Number) is a 13-digit code printed on the back cover of every textbook. The edition number — like "5th Edition" or "2024 Edition" — matters because publishers change problems, examples, and page numbers between editions. Buying the wrong edition means your homework problems will not match the book, and you will not be able to resell it.

Your syllabus should list the ISBN. If it does not, check your school's bookstore website — search for the course name or number, and the bookstore will show you the exact ISBN and edition required. Write this number down or take a screenshot. When you search for the book on other websites, search by ISBN rather than title, because that guarantees you get the exact version.

Step 3: Compare prices across at least four sources

The same textbook can cost $40 used on one site and $180 new on another. Check your campus bookstore first, then search the ISBN on Amazon, Chegg, VitalSource, and at least one used marketplace like ThriftBooks or AbeBooks. Write down the price at each place, including shipping and any rental periods.

Campus bookstores often have the highest prices, but they also have the easiest returns and sometimes offer rental programs. Amazon usually has competitive prices on new books but may not have used copies. Chegg specializes in rentals and used textbooks. VitalSource sells digital versions, which are usually cheaper but cannot be resold. Used marketplaces often have the lowest prices but may take longer to ship and have stricter return policies.

Do not forget to factor in how long you need the book. If you only need it for one semester, renting is almost always cheaper than buying. If you are keeping it for reference after the course ends, buying used and reselling it later may cost less overall than renting.

Step 4: Check your school's textbook rental and library programs

Many schools run their own textbook rental programs through the campus bookstore or library. These programs let you rent textbooks for the semester at a fraction of the purchase price — often $20 to $50 per book. Check your school's bookstore website or library website for a "textbook rental" or "course materials" section.

Some schools also participate in textbook sharing programs where students can borrow books from each other through an app or online platform. Ask your school's bookstore or library whether they offer this. It is usually free or very low cost. If your school has a course reserves system, search for your course there — books on reserve can usually be checked out for a few hours at a time, which works if you need the book for studying but not for keeping at home overnight.

Step 5: Read the return policy before you buy

Different sellers have different rules about returns. Campus bookstores usually allow returns within 2 to 4 weeks if the book is unused and you have your receipt. Amazon allows returns within 30 days. Chegg allows returns within 30 days of rental. Used marketplaces like AbeBooks often do not allow returns at all, or only within a very short window.

Digital textbooks from VitalSource and similar platforms usually cannot be returned once you have opened them. If you are unsure whether you need the book, do not buy a digital version — buy a physical copy from a seller with a return policy instead. Before you complete your purchase, take a screenshot of the return policy. If something changes in your course — the professor cancels the textbook requirement, you drop the class, or you find a cheaper copy — you will know exactly what your options are.

Step 6: Decide between buying, renting, and borrowing

Once you have prices and return policies, you can make the actual decision. Here is how to think about it:

• Rent if you only need the book for one semester and will not reference it after the course ends. Rental is almost always the cheapest option for a single semester.
• Buy used and plan to resell if you need the book for the full semester and think you can resell it afterward. Used books are cheaper upfront, and you can recover some money by selling them back to the campus bookstore or online marketplaces after the course ends.
• Borrow from the library or a classmate if you only need the book occasionally and can work around someone else's schedule.
• Buy new only if you will keep the book for reference after the course ends or if the used price is close to the rental price.

After you make your choice, set a reminder on your phone for the return deadline if you bought the book. Many students lose money because they miss the return window by a few days.

Frequently Asked Questions

Can I use an older edition if the syllabus says a specific edition is required?

Ask your professor first. Some professors require a specific edition because homework problems changed, but others are flexible. If your professor says an older edition is fine, you can save $50 to $100 by buying the previous version. If they say no, they usually have a reason — the page numbers or problem sets will not match.

What if I buy a textbook and then the professor says it is not required?

Check the return policy immediately. Most campus bookstores allow returns within 2 to 4 weeks if the book is unused and you have your receipt. Online sellers like Amazon allow returns within 30 days. Act quickly — the longer you wait, the harder it is to return the book.

Is it better to buy or rent a textbook?

Renting is cheaper if you only need the book for one semester. Buying used and reselling it later can be cheaper if the used price is low and you think you can sell it back. Buying new only makes sense if you will keep the book for reference after the course ends or if new and used prices are very close.

Where can I sell a textbook after the semester ends?

Your campus bookstore usually buys back textbooks at the end of each semester, though the price is often much lower than what you paid. Online marketplaces like Amazon, AbeBooks, and Chegg also buy used textbooks. Compare prices at all three before you sell — the same book can have very different buyback values at different places.

What if I need a textbook but cannot afford it?

Talk to your professor and your school's financial aid office. Some professors have copies available to borrow, some schools have emergency textbook funds, and some offer short-term loans specifically for course materials. Your school's bookstore or library can also tell you about rental programs and course reserves that cost less than buying.
