Got My Workbook

My class will soon end but I just got my workbook today :-) Well, it was first said that it is not required but our instructor requires it. I could have bought it online, through Amazon or Barnes and Noble, but I don't want to use my own money to purchase it. It costs around $32, price and tax. Our instructor told the school that the bookstore should get it in order for those that don't have it can get the book. On Saturday one of our classmates told us that the bookstore has it already. I went there this afternoon and got the authorization from the Cashier to get my workbook at the bookstore. I used my remaining scholarship money to pay for it, hence I got it for free :-)
