Public Schools and the Second World War by David Walsh and Anthony Seldon has been reduced to $2.99 from $12.99. It was on my wishlist AND I just happened to have $3 in my Kindle Rewards credit. I suppose its happening on double points day was the icing on the cake, but I can't get all that excited by an extra 9 points.
