Bookwalker discounts! Sasaki maybe?

Ohh, lots of discounts available for light novels in Bookwalker right now. I'm tempted to get the remaining volumes of Sasaki to Piichan as I really loved the ones I read so far...
I've been staving off buying new volumes for quite a few months as I had to go through those I already bought. You know that feeling when you have so much and yet want to buy more? It happens often with Steam sales too...

So far my highest priorities are Sasaki to Piichan, Ore wa Seikan Kokka no Akutoku Ryoshu and maybe Seiyuu Radio no Ura Omote...
