Used Textbooks for School

I am returning to school in pursuit of paralegal certification and licensing, and eventually a full Associates Degree in the legal field.  I am having some difficulty purchasing the necessary textbooks for my courses, and so I am hoping that someone will be kind enough to donate funds that I can apply towards this purchase.

Below is a table reflecting the costs of these text books used and new.  I will also be conducting ongoing searches to find the most cost effective versions of these textbooks available to me.
