Physics 20 series textbook: Giancoli 7th ed. ($150)

Just finished up the whole course series and looking to sell my copy of Giancoli (7th ed.). This is the textbook used for the summer physics courses as well. The corners and edges of the book definitely have a bit of wear on them, but all pages are intact and have no highlighting or writing. Selling for $150--way less than the bookstore is asking!
