I ordered volume 9 online at CDJapan. Their price is roughly around the same as Amazon’s but there is an option for cheaper shipping which is a definite plus!

My wallet now hates me but my inner fangirl is squealing in delight. Said wallet is not going to be happy when it finds out that I’m going to be order a few shirts (number will depend on whether designs for the frontier twins are made) from Gallant Designs on Red Bubble.
