If, like me, you are struggling to make your Waterstones order up to £15 to get free delivery, these World Book Day books may be useful. I suppose they could help someone get to £35 too, in order to use the £5 off voucher (WE9789)
There are 17 books available, fiction and non-fiction, priced at either £1 or £1.99. Some of them seem worth a read - Ricky Tomlinson, Alan Carr, John Simpson, Doctor Who, and quite a few childrens titles.
Or, if you have any small people in your life, most of the Mr Men and Little Miss books are on offer at £1.39 at the moment.
I hope this info is helpful to someone.
