So why are blockbuster sales down? “One explanation is that traditional bookstores are suffering because the big supermarket chains have moved into bookselling. Another is that all the big releases were bunched together to avoid the anniversary of 11 September, and with only so many book buyers to go round it was inevitable sales would drop. Price could also be a factor, with hardback novels in the US costing $25 or more – steep in these recessionary times.”
