I've seen US business series textbooks as well as a few Psych printed in black/white with plain covers. They were custom printed for a college/university. Even one of the Penn Foster textbook kits I received was custom printed black/white.

I'm not disputing there may be international versions that are black/white, but the same holds true for US versions.

I've come across several custom editions, too. They're way cheaper than the US editions and international editions, but I'm not sure if their content are the same. Are they?
