A lot of books.
TBD have been good to me for awhile now; rarely sending me yellowed/damaged books. 8/9 of my ordered Drifting Classroom volumes have arrived, all were sealed on arrival and only volume nine has a knock. Impressive, considering the four Suikoden books I ordered from them and a number of others in the past were sent in poor condition.
However, sadly for me it seems Amazon - who I had faith in - have decided to play the role of book villain this time around. I ordered Gantz 1-2 from them. Volume one arrived sealed and new. Volume two arrived unsealed, yellow, the cover pages are bent outward and a page has been bent in the middle of the book for bookmarking purposes. Le sigh... At least I can read it before sending it back.
The other books from them weren't as bad, thankfully... though one Yotsuba spine has white marks/a few tiny pieces missing from it and the other volume has knocks. Nothing to cry a river over, but annoying.
List:
Drifting Classroom 4, 6-7 & 9
Gantz 1-2
Yotsuba 2-3
MPD Psycho 2
