I just bought a older edition textbook for 15 dollars, whereas the newer one would run me around 60 dollars. About 80% of this old book is same as the new, so there are some minor annoyances when page 383 in the new book turns out to be page 384 on mine. big whoop.
so, the more often they publish and "revise" new editions, it will drive the older version worthless. (i'm sure you all had a similar situation, my $150 Chem book is now 9 dollars 3 years later).
Since the older is as good as new (sans the aforementioned annoyances), we basically are paying a lot less for textbook.
