Nook is selling 100 of 2013's most popular books for only 99p for a new promotion.
Bestselling titles including Eleanor Catton's Man Booker Prize-winner The Luminaries (Granta), Billy Bryson's One Summer: America 1927 (Transworld) and Donna Tartt's The Goldfinch (Little, Brown) are all included in the offer, alongside books such as Khaled Hosseini's And the Mountains Echoed (Bloomsbury), Charles Moore's Margaret Thatcher: The Authorised Biography (Penguin) and Chimamanda Ngozi Adichie's Americanah (HarperCollins).
Many of the titles in Nook's 100 Best Books of 2013 offer are being price-matched on Amazon.
For a title such as The Luminaries, which has an RRP of £18.99, the deal offers a saving of 95% on the full price. A wider range of titles is being sold as part of a "January Sale" on the site.
Iain Chapple, sales, marketing and digital director at Granta, said the offer represented good value for readers.
He said: "It's obviously a fantastic price to get a Man Booker Prize-winner for, especially when it's usually priced at £18.99. We're actually quite heartened to see a retailer like Nook making such strong promotions and building its place in the market – I think a lot of e-book retailers have been doing that over the Christmas period. It shows that there is some confidence there."
He added: "A lot of people are concerned about promotions like this devaluing e-books, but we've always seen good sales rates continue after a promotion. The offer helps to widen the readership, and people will buy it at full price on the back of it."
However, an independent bookseller said it was a shame that popular titles were being sold so cheaply.
Sarah Donaldson of Red Lion Books in Colchester said: "We sold a lot of copies of The Luminaries and The Goldfinch over Christmas and were very happy with how they did – it showed people still have an appetite for big hardbacks. It doesn't seem to be a helpful move for us to now see them sold at 99p. If you had bought it as a Christmas present and now saw it priced like that, it would devalue it for you entirely."
Google Play has been running a similar Great Book Sale over the Christmas period, selling frontlist titles such as The Goldfinch for £1.99.
