To get 10% off all purchases at the Penn Bookstore, simply tell the cashier you are a Barnes & Noble club member. They don't ask for your phone number or anything. Update: Unfortunately I think this was one nice cashier before school started, who gave me a discount. You can always ask for a discount; sometimes people are nice and they give you one. I'll be buying my books either at BetterThanTheBookstore or at Amazon.

Liked what you read? I am available for hire.
