While most people tend to focus on the big deals on things like TVs or laptops on Black Friday, it’s also a great time of the year to buy books. Yes, actual print books, not Kindles (although Amazon does have sales on a bunch of Kindle models too, should digital be more your speed.)

Here’s where you should be looking if you’d like to build out your library this Black Friday.

(And if you’re stuck for book ideas, check out The Verge’s Holiday Gift Guide or our Thanksgiving book round-up for some suggestions!)

Amazon

Amazon is offering $10 off any book order of $25 or more from Amazon, with the discount code HOLIDAYBOOK. The deal applies once per account, and it’s good through November 28, 2016 at 02:59am EST. Just a few caveats: the book has to be sold directly from Amazon (so no third-party sellers or used books), and print books only (no so Kindle books). Other than that, it’s good on pretty much any book on the website.

Barnes & Noble

Barnes & Noble is also offering big book discounts, offering 30% off any item they sell (excluding devices, digital NOOK Books, and LEGO products) with the discount code BNFRIDAY16.

Additionally, Barnes & Noble is offering a huge selection of signed books in-stores this weekend, with titles from tons of popular authors available. Check out the full list here, to see if there’s a copy close to you!

Book Outlet

While less well known than Amazon or Barnes & Noble as a bookstore, Book Outlet is a great website that sells brand new surplus inventory directly from publishers at massive discounts off sticker prices. While the selection varies, there’s usually plenty of great books to be had, and this weekend the site is offering an additional 30% off any orders across the entire site.
