Buying Books Vs. Renting Books

My husband decided to  rent the books he needed for his classes in pursuing his master's degree.  He rented those books at Barnes and Noble inside  Doquesne University campus.  His classes for the first semester has ended  last week and he got good greats.  He is enrolled again for the second semester and decided to buy  the books new online because it is cheaper than renting it.

I took these shots inside Barnes and Nobles when hubs was goofing around and the little Miss was busy looking at something.  He is doing his  classes online and I admire him for his perseverance in continuing his  education.
