ThriftBooks Discount Codes — Used Books at Second-Hand Prices
ThriftBooks sells used and new books from a catalogue of more than 13 million titles, spanning children's books through to rare collectibles. Because most stock is second-hand, the price is already well below cover — the real skill is knowing how condition, shipping and the rewards scheme interact, because that is where a cheap order turns into a genuinely cheap one.
Who ThriftBooks Suits
It is built for volume readers and rebuilders of shelves: someone working through a series, a student buying set texts, a parent restocking. If you need a pristine first printing, this is the wrong shop. If you need the words on the page for a fraction of retail, it is close to unbeatable.
What You Can Buy
- Used books across every mainstream genre, the bulk of the catalogue.
- New books where used copies are unavailable.
- Children's and young adult titles.
- Rare and collectible editions.
- Textbooks and academic titles.
Reading the Condition Grade Before You Buy
Every used listing carries a condition grade, and it is the single most important field on the page. The grades describe cosmetic wear, not readability — a lower grade almost always means a readable book with scuffed edges, a cracked spine or a previous owner's name inside the cover.
The practical rule: for something you will read once and pass on, take the cheapest acceptable grade, because the price gap between grades is often larger than the difference you will notice. For a gift or a book you want to keep, pay up a grade or two. Where a listing mentions markings or highlighting, that matters more in a textbook than in a novel.
Making the Shipping Threshold Work
Standard shipping is free on US orders over $20, and on a site where individual books often cost a few dollars, that threshold changes how you should shop. Buying one book at a time is the most expensive way to use ThriftBooks; building a basket to clear $20 usually costs less in total than two separate small orders.
Orders arrive in recyclable packaging, and it is worth ordering a series together rather than book by book — both for postage and because used stock moves, so the sequel you assumed would be there next month may not be.
ReadingRewards, and Whether It Is Worth It
The loyalty scheme is called ReadingRewards, and members earn towards free books as they buy. The mobile app awards bonus points on purchases over the website rate, which is the detail most people miss — if you buy regularly, placing the order in the app rather than the browser is free money.
Rewards work best for consistent buyers. For a one-off order, a code applied at checkout will beat points you have not yet accumulated, so use the offers above instead of waiting.
How to Save at ThriftBooks
- Apply a live ThriftBooks code from the offers above at checkout.
- Build the basket past $20 for free US shipping rather than ordering singly.
- Join ReadingRewards and order through the app for bonus points.
- Drop a condition grade on anything you will read once.
- Buy a whole series in one order while the stock is listed.
Best Time to Buy at ThriftBooks
Textbook demand spikes at the start of each academic term, so buy set texts early rather than in the rush. Sitewide promotions cluster around Black Friday and the December gifting period, with clearance in January. Browse more book and media discount codes or education offers for September 2026.
Hunting Out-of-Print and Hard-to-Find Titles
The second-hand market is where a used bookseller beats a new one outright. Out-of-print titles, discontinued editions and books that never had a digital release only exist as used copies, and a 13-million-title catalogue is a genuine advantage there.
Two habits help. Search by ISBN rather than title when you need one specific edition, because popular books carry dozens of printings with different pagination — which matters for study texts where page references are set. And if the exact edition you want is listed once at a fair price, buy it; unlike new stock, used listings are single copies and do not come back.
