You already know that the textbook system is a scam.
Publishers often crank out new editions without making substantial changes.
Schools follow standard procedure over saving students money.
And sometimes a class hardly uses the textbook at all.
And keep in mind that none of these alternatives come without some risk involved.
Determine what route to take given your own academic goals and what it takes to reach them.
This means is that it’s possible for you to buy essentially the same book for less.
With each older edition, prices drop significantly.
It’s up to you what risks you take, as well as how much money you save.
