One eagled-eyed Amazon shopper noticed that the online retail giant is selling a range of books for just £1 as part of the upcoming World Book Day.
World Book Day is an annual event that aims to promote reading for pleasure among young people, giving every child the opportunity to take home a book.
The books on Amazon are not available yet, but can be pre-ordered ahead of their release on February 17 — with World Book Day following shortly after on March 3.
