college textbook

A poorly written "book" that you are forced by naive professors to purchase at outrageous prices. To curb the used market, the pages are renumbered, the cover changed, and the book republished as a "new edition" every few years.

Person #2: Do you remember what you paid for them?
Person #1: Yeah, $600. Why?
Person #2: Never mind...
