- Type the ISBN(s) from your book(s) into the Cash4books.net form on the homepage. Press the
Enter key after each ISBN. Click 'price my books' to see our offer. - View your Seller Cart, then go through Checkout to give us your contact information. Please thoroughly read our book condition requirements.

Are there any fees to use Cash4Books.net?
No. Our service is free to use; there are no hidden fees.
Can I sell used textbooks here?
Yes! Sell your textbooks online at Cash4Books.net, in addition to any other books you may have. As always, we offer instant price quotes, free shipping, and fast payment!
A suggestion for all college students: print out our price quotes, and take the printout with you to your local college textbook buy back. If we are offering more, then sell your textbooks back to us instead! Be sure to submit your textbooks the same day to Cash4Books.net, in order to lock in your textbook price quotes.
Do you price match?
Yes. We update Cash4Books.net constantly in an attempt to give you the best price we can for your books. From time to time, however, we miss an opportunity and we don't want to do this! Give us a chance and we will show you.
If you have found a better price elsewhere, please email us with the ISBN, the name of the online competitor, and the price that they quoted. We will promptly reply to let you know if we will match their used price quote.
Will you buy more than one copy of the same book? What if I have multiple copies of the same books?
Yes, but we do impose a maximum. Our seller cart will indicate how many of each book we will purchase. Just look for "MAX=" for each book in your cart. After entering the ISBNs, go to "View your seller cart" to change the quantities.
I have a LARGE number of books. Will you be able to help me?
If you already have your ISBN inventory in electronic format, you may contact us, and we will price your inventory for you.In addition to our regular online book buying program, Cash4Books.net also occasionally buys books by the pallet. If you are a book wholesaler or distributor and would like to establish a business relationship with us, please contact us.
| We also buy large quantities of books directly from colleges and charities.
Furthermore, Cash4Books.net is now offering a bar code scanner rental service. The purpose of this program is to provide our customers with a relatively inexpensive way to quickly and easily price check large quantities of books, and optionally create an electronic inventory. The price is only $5 per week, plus shipping, and a refundable deposit. Our website will accept EAN-13 bar codes, which are located on the back cover of most books (these begin with 978). |

- Advance reading copies, uncorrected proofs, and/or promotional or "screener" copies of books
- Book club editions

What is an International Edition?
These are editions of US textbooks which are printed and intended for sale in a non-US market. These books may have a different ISBN but usually have the same content as the US version. They are often bound with a soft cover and printed using lower quality materials. They usually have a statement such as "international edition" or "economy edition" and "Not for sale in the USA" somewhere on the cover. Cash4Books.net does not buy International editions.
Do you buy collectible books or offer appraisals?
Sorry, Cash4Books.net only buys newer books that have an ISBN number. We do not offer an appraisal service for collectibles.
Will you accept books in any condition?
Books will not be accepted with any of the following:
- Fire or smoke damage
- Major wear to the binding
- Medium to large tears to the cover or pages
- Missing pages
- Strong odor of any kind (including cigarette odor)
- Water, moisture damage, or mold
- Workbooks or manuals with writing in them
Will you purchase books with missing CDs, missing dust jackets, writing, underlining, and/or highlighting?
If a book originally came with a dust jacket, CD or DVD, it must accompany the book when shipped to us or the quoted price may be reduced.
Other conditions that may result in a reduction of the quoted price:
- Excessive writing, underlining, and/or highlighting
- Remainder marks on page edges (publisher's overstock)
A small amount of writing, underlining or highlighting of pages is usually okay, as long as it is on fewer than 20% of the book's pages. However, workbooks, lab manuals, study guides, and books with practice tests will not be accepted if they contain writing. If a textbook originally came with a CD or DVD, the original CD/DVD must accompany the book when shipped to us. The CD/DVD must be in working condition. Computer manuals and language courses originally issued with a CD will not be accepted without.
McKenzie Books reserves the right to determine item condition upon receipt in our warehouse. Items not accepted by McKenzie Books will only be shipped back to the Seller at the Seller's expense. Items not accepted will be held for 30 days; after that time, these items will be discarded or donated. Please see our condition requirements for more details.
Do you buy ex-library books?
No.
ISBNs
What is an ISBN number?
An ISBN is a 10 or 13 digit number that can be found on the back cover or inside the front cover of almost all books. You may enter the ISBN with or without the dashes, and don't leave off the leading zeros. Sometimes an ISBN can end with an X. Cash4Books.net will accept either the 10-digit or the 13-digit ISBN. Examples:
978-1-888799-97-2
1-888799-97-8
13-digit ISBN's should start with the numbers 978. Your book may have a 10-digit ISBN, or a 13-digit ISBN, or both (if your book has both, only enter the 13-digit number).
Where do I find a book's ISBN number?

The ISBN is usually found on the back cover, immediately above the barcode.
If you cannot locate your book's ISBN on the outside of the book, open the front cover and look on the page immediately following the title page. This should be the copyright page and will include information about the copyright date, the author and publisher. The ISBN is a 10 or 13 digit number, and it should be in the middle or at the bottom of that page. If the book is pre-1970s, then it may not have an ISBN.
What if my book does not have an ISBN?
Sorry, but we do not purchase older books and/or collectibles without ISBN numbers.
My seller cart
How does the seller cart work?
Your seller cart works similar to that of a shopping cart on other online sites. When you enter a book to sell, and if we are currently buying it, then it will automatically be added to your Cash4Books.net seller cart. Your books will be automatically totaled up for you. You may also adjust quantities via your seller cart.
Should I create a separate order (seller cart) for each box of books that I have to sell?
Yes, a separate order (seller cart) for each box of books that you are selling would work best. This will make things run more smoothly once they arrive in our receiving department.
Can I save what is added to my seller cart until I am officially ready to sell?
Yes, the books in your seller cart will be automatically saved for up to 48 hours.
How do I take books out of my seller cart?
Simply click the "remove" button next to the price quote.
If I make a mistake, how do I cancel my order?
If you have not yet submitted your order, you can simple click "Empty my Entire Cart." If you have submitted your order and it is in "Approved for Shipment" status but have not yet mailed your books, you can cancel your order by going to your account and clicking the "Cancel" link on the right hand side.
If you have already mailed your books, let us know and we will send them back to you after we have received the payment for return shipping.
What happens if my books do not meet your condition requirements, and you do not accept all of them?
Items not accepted by McKenzie Books will only be shipped back to the Seller at the Seller's expense. Items not accepted will be held for 30 days; after that time, these items will be discarded or donated. Please make sure you are familiar with our condition requirements.
Why don't you buy all of my books?
Some books may be in over-supply in the market. Please check again as our database is updated every day. For examples of books we are buying, please see our Example 500 list which is updated every day and also shows prices paid for books which meet our condition requirements.
How do you decide which books to buy?
We base our prospective purchases on supply and demand in the market. Our database is constantly changing. For examples of books we are buying, please see our Example 500 list which is updated every day and also shows prices paid for books which meet our condition requirements.
How do you determine prices for books?
We constantly evaluate the market's supply and demand. This allows us to offer the best prices. We constantly update our database to insure you get the best prices possible for your books.
We keep our pricing simple and offer one quote for each book that meets, or exceeds, our condition requirements. The price quotes are based on the assumption that your books range from very good to new condition, and that they meet all of our condition requirements. We reserve the right to determine condition and may take deductions from the original price quote, if necessary.
Checkout and creating an account
What do I do when I have finished adding books to my seller cart?
After you are finished adding books to your seller cart, you may proceed to checkout. At this time, we will ask that you create a new account with Cash4Books.net, or login to an existing account. We ask for your contact information so that we may efficiently contact you and complete this transaction. The final step that will need to take place on the checkout screen is for you to confirm and submit your order to us. Note: We ask that your books be shipped to us within one week of the order date. If you do not make it to the Post Office in time, please submit a new order.
Is my personal information secure?
We do not provide any personally identifiable information about you to any third parties without your permission, unless those third parties have agreed to our confidentiality provisions and only use the information to help us operate the site, or as we are required by law to disclose such information. We may occasionally post links to third party sites on our site. Once you click on a link, you may be sent outside of Cash4books.net. Information you give outside of Cash4books.net is not protected by our privacy policy.
I forgot my password. What do I do?
There is a link at the end of the Login screen "Forget your password? (click here)." This will direct you to a page where you can enter your email address to have a password reminder sent to your inbox. You can then access your own email account for your password.
How does the shipping work?
I am ready to send the books to you. What do I do?
Once you submit your books to us, you should receive an email with a link to instructions. Another way is to login to your account, and look for "Approved for shipment" status and the "print & ship" button below.
How long do I have to send in the books?
We require that all orders be put in the mail within 7 business days of placing the order. You will be sent a friendly email reminder. This is because of the constant fluctuation of current prices. If you mail your books after the 7 day period, your order may be cancelled, and a new order with current prices will need to be created.
Do I have to pay for postage to get my books to you?
No. We will pay the shipping and provide instructions after you submit your books.
I am unable to print from my computer. What do I do?
If you are unable to print, then you have two options:
- We can mail you some shipping labels, just request them from us.
- You can pay for the shipping initially, and once we receive your order, we will add a shipping credit on to your order total. This amount will be the equivalent of USPS Media Mail rates, based on the weight of the books. If you do this, you may wish to ask for "Media Mail" at your Post Office.
How do I know the status of my order, and whether you have received my books?
We will send out a "received" email notification as soon as your shipment is received. Please keep in mind that Media Mail takes up to 14 business days. Plus, please allow a few days for processing. Once your books are received, they must be inspected. You may also login to view the status of your order(s) at any time by going to your account. After your books are inspected and marked as "processed", payment will be issued. Payment is initiated within 1-3 business days of "processed" status.
What happens if I forget to include the packing slip?
If you let us know, we will look up your order by your name or email, and then make a note to print a packing slip when your package arrives. As long as you put a return address on the package, we should have no problems processing your order.
What happens if I do not include some of the books on the packing slip?
We will send out a "received" email notification and inform you about the missing titles and whether there was any damage to your package. We will hold your items and wait for your reply and after 14 days we will go ahead and process your order as is.
What if I pack the wrong book or a different edition?
We will first check to see whether the item(s) belong to another of your orders. If not and if we are buying the item, we will remove the previous item from your order and add the new edition or book. If we are not buying the item(s), we will hold it for 30 days; after that time, these items will be discarded or donated.
What happens if I include books in the box that are not on the packing slip?
We ask sellers not to include books that are not on the packing slip. We will first check to see whether the item(s) belong to another of your orders. If not and if we are buying the item, we will add it to your order. If we are not buying the item(s), we will hold it for 30 days; after that time, these items will be discarded or donated.
What happens if you do not receive some or all of my books?
We will send out a "received" email notification and inform you about the missing titles and whether there was any damage to your package. We will hold your items and wait for your reply and after 14 days we will go ahead and process your order as is.
Can I use a different shipping carrier?
You may choose to use a different shipping carrier, however, please keep in mind that we will only credit you the USPS Media Mail rates, based on the weight of the books. The books will be weighed on arrival.

Why don't you offer a premium for "New" or "Like New" books?
The two main reasons are time and efficiency. We have received a great deal of positive feedback for the ease of use of our site, and it has been designed for the purchase of buying used books. If you are a new book wholesaler or distributor and would like to establish a business relationship with us, please contact us.
