World of Books referral code: Get £5 when you sell £10 of books

If you have unwanted books, CDs, DVDs or video games at home, the World of Books referral offer is an easy way to get a little extra for them.

New World of Books Sell Your Books customers can currently get a £5 bonus when they complete an eligible first trade worth at least £10 using my referral link.

World of Books Sell Your Books was previously known as Ziffit, so if you were searching for a Ziffit referral code or Ziffit £5 bonus, this is the service you’re looking for.

Get the £5 World of Books referral bonus

Use my referral link below to register for the offer:

World of Books £5 referral link

You’ll need to be a new customer and complete an eligible first trade worth at least £10 to receive the £5 welcome reward.

I may also receive a reward if you use my link and successfully complete your trade.

World of Books confirms that its Refer a Friend programme gives a welcome reward to new customers, which is added to an eligible first trade. (World of Books Refer a Friend)

How to claim your £5 World of Books bonus

Start by opening my referral link and registering for the offer.

You can then scan the barcodes on your unwanted items using the World of Books Sell Your Books app. If you’d rather use the website, you can enter the ISBN or EAN manually.

World of Books gives you an instant price for each item it wants to buy. Keep adding eligible items until your first trade reaches at least £10, then complete the trade following the referral instructions.

World of Books currently buys books, textbooks, CDs, DVDs and video games. What it accepts and how much it offers can change according to demand and the amount of stock it already has. (World of Books)

£5 referral or WELCOME10: which offer is better?

There is another new customer offer worth knowing about.

World of Books currently advertises the code WELCOME10, which gives new customers an extra 10% on their first trade. (World of Books welcome offer)

Which is better depends on how much you’re selling:

So, if your first eligible trade is under £50, the £5 referral offer is worth more. At £50 they’re equivalent, while above £50 the 10% WELCOME10 offer becomes more valuable.

There is another important point here. World of Books’ terms say its promotional offers cannot normally be used together unless otherwise stated. (World of Books terms)

I would therefore choose whichever offer gives you the better bonus rather than expecting to receive both.

How does selling books to World of Books work?

The service is designed to be much simpler than listing every book individually on a marketplace.

Scan a barcode and World of Books gives you an instant offer. If you’re happy with the prices, complete your trade, package everything together and use the free shipping service.

World of Books currently offers free shipping using InPost and DPD, with home collection available for larger trades. Once your items have arrived and been processed, you can be paid by PayPal, bank transfer or cheque. (World of Books How it Works)

There are no individual listings to create and you don’t need to wait for someone to buy each book.

Is there a minimum trade?

For the £5 referral bonus covered in this article, aim for an eligible first trade of at least £10.

World of Books’ standard rules are slightly confusing because different pages currently describe the normal minimum differently. Its formal terms state a minimum trade of 10 items and £5 total item value, while parts of its website describe it as 10 items or £5.

For the referral offer, the important thing is to follow the conditions displayed with your referral reward and make sure the eligible value remains at least £10.

What condition do my books need to be in?

World of Books checks items after they arrive.

This is worth paying attention to because rejected items aren’t returned to you. World of Books specifically advises sellers to consider this before sending their items. (World of Books Sell My Books)

I wouldn’t send a rare, signed or potentially valuable book without checking its value elsewhere first.

For ordinary books that you simply want to clear out, the service is more appealing because convenience is the main advantage.

Will I get more money selling books elsewhere?

Possibly.

World of Books is convenient, but that doesn’t mean its instant offer will always be the highest price you could get.

If you have a valuable textbook, recent release, box set or collectible book, check what it’s worth elsewhere before accepting the offer. Selling it individually could get you more money.

For a pile of ordinary books, however, there’s a trade-off. Selling them yourself means creating listings, potentially taking photographs, waiting for buyers and sending multiple parcels.

World of Books lets you scan everything and send the accepted items together for free.

The £5 referral bonus on a £10 first trade makes that convenience particularly attractive for a relatively small clear-out.

Is World of Books Sell Your Books the same as Ziffit?

Yes. If you previously used or heard about Ziffit, the service has been rebranded as World of Books Sell Your Books.

That means people searching for a Ziffit referral code, Ziffit £5 bonus or Ziffit Refer a Friend offer should now look at the current World of Books Sell Your Books offers.

Your old memories of scanning barcodes and sending books away aren’t wrong. It simply has a new name.

Is the World of Books £5 referral offer worth using?

For a first trade between £10 and £50, the current referral offer is particularly good because the flat £5 bonus is worth more than the alternative 10% WELCOME10 offer.

On a £10 qualifying trade, for example, an extra £5 represents a 50% boost to the original trade value.

I wouldn’t use World of Books blindly for something potentially valuable, but for unwanted books, DVDs, CDs or games that are otherwise sitting around the house, it’s a simple way to turn them into some cash.
