| i went on the penn bookstore website, via campus express, entered my courses, they gave me my textbook list and i looked at the book, author, and edition number and then went on ebay and amazon to look for the texts under those specifications. i ordered a new psych book on amazon for the same price as a used one on the penn bookstore. on ebay i'm bidding for another new text for like 50 bucks under the penn bookstore price |
