For 2008 Nielsen BookScan, which tracks nearly all retail book sales, reported
consumer sales in the UK market of £1.773 bn and 236.9 books. This is an average
selling price (not cover price) of £7.49 per copy.
The figures show a decline from the previous year of 0.4 per cent (by volume) and 1.6
per cent (by value). The average selling price fell by 8 p and is at its lowest since
the data was first recorded in 2001.
The Bookseller commented that one reason for the falls was the spectacular success of
Harry Potter and the Deathly Hallows in the previous year. When the book was
published on 21 July 2007, it sold 2.6m copies in the UK on that day alone. There was
no similar title in 2008.
