Your books will have a barcode, an ISBN, or both. Either scan the barcode using the app or type all of the numerical digits above or under the barcode into the search box, including any at the beginning or end of the sequence that may be smaller. The ISBN might be on the publishing details page at the front of your book. If it does not have an ISBN, then we cannot accept it.

The ISBN is a 10 or 13 digit number that is unique to each book. It appears next to the barcode on most books and in instances where it doesn't it can be found on the publishing page.

A barcode is a machine-readable representation of the ISBN. This information relates to the product it is attached to. It looks like a series of vertical lines differing in thickness.

This is not something we offer at this time.

Unfortunately we cannot accept ex-rental media products.

Unfortunately we can't take your promotional or not for resale items.

We try to accept as many items as we can. However, our acceptance rate is based on several factors including current market demand and availability, so this does frequently change.

Our offer prices change frequently depending on market demand, and how many of the items we have in stock currently. We offer good value alongside our free drop-off service.

You automatically accept the offer price when you press 'complete trade.' Remember, you need to meet a minimum $7.50 value to complete a trade. You can always remove individual items from the trade if you're not happy with our offer price, by clicking the minus button next to the item.

Once you complete a trade, the prices offered for your items will be fixed for 28 days. If you choose to save a trade or leave items in your basket, the offer price will be guaranteed until midnight on the day the offer was made.
What does it mean when I save a trade?

It may not always be convenient to complete a trade or you may have additional items you want to add to your trade at a later stage. For your convenience you can save your trade and come back to it whenever you want to. In order to save a trade you need to be a registered user.

We offer fair value and don't take competitors offers into consideration so we are unable to price match.

If you visit 'My Account' and view the expired trade there will be an option called 'Recalculate'. Upon pressing this button we will re-check the current value of your expired trade and add it to your basket (some items may be rejected).

With our bulk uploader tool, you can scan up to 500 ISBNs in one go. You’ll just need to request access in the ‘My account’ page. Once approved by our team, you’ll be able to see the bulk upload icon below the ‘Log Out’ button. Click on the icon, and you’ll find all of the information on how to get started.

There is no limit on how many items you can send us. You will need to reach a minimum value of $7.50 before you can complete your trade.

Once you’ve submitted your World of Books trade on our website or app, you’ll receive an email from us within 24 hours with your shipping label attached.

If you have more than one box, you can download up to 10 additional labels from your account page on our website. To do this, select ‘View’ on the trade number that you’ve just created and then ‘Request additional labels’. We’ll email the additional labels to your email address.
