Kobo has a 50 % off coupon on books published with KWL(= Kobo Writing Life), which means you can get The Cauldron Bound for just 1.49, while I get paid for the full price!  There are also a lot of other books available.  Sadly, I have no idea if the coupon works in other parts of the world than the ones listed below.  But happy shopping!
