Selling the Math 51 Levandosky textbook for $20.

The Stanford bookstore sells it at a ridiculous ripoff, don't buy it there.

Amazon runs between 30-40 depending on season.

Buy it from me for $20 and ensure that the only reason you cry is because of the class material and not the silly price of the textbook!
