Purchasing the book through your campus representative is cheaper. We sell the book to them with a discount and they pass the savings down to you. By buying from them you also won't have to pay for shipping!

We give a 10$discount to the local representative and they usually choose to offer the book at 5$ less than the internet price + you save 6$on the shipping so overall you will save 11$ if you buy from them.

By keeping 5$in your pocket, and putting 5$ in your local representative's pocket, one part of the profits from this book will stay in your university.

Stay local.
