So, I decided I to check out your books Mr. Radthorne and browsing Amazon I noticed something odd... They have The Road to Kotaishi, Parts 1&2, listed for ~$12 each. However, there's also a listing for what looks like a single volume with both parts for $33! What's up with that? I haven't even seen mention of a single volume on what I read around here. Plus, since when is buying an omnibus (for lack of a better term) more expensive? And for that matter, $12 for a Mass Market Paperback? Aren't they usually $7-$8? I know I'm coming off as a cheepskate here, but I have limited disposable income....and eventually I'd like to buy all four books.
