No1 Best sellers like Fifty Shades of Grey and The Hunger Games are on sale everywhere at very low prices. I have seen all three Hunger Games for as low as £5.00 and Fifty Shades of Grey is currently on sale at £3.00 on Amazon although the books are still at a normal price in the USA.
These are books people are out to buy and the shops could hold the price much higher and not only make themselves bigger profits along with the publisher and author but help keep the dying industry alive. This would then allow the bookshops to feed some of the profit back into promoting the lesser known books and increase there sales. It's all upside down.
The shops are killing themselves. Why would someone buy a No1 best seller for £3 from ASDA and then pay £7.99 for another book. They either buy it in ebook form or wait.
