There is this good book for a great deal compared to the actual website rx-perts which sells the book for $160. I just got mine for $135. There's actually a few copies left right now. Pretty good price. Also they are 2012 editions too so know you have the most updated versions and info.
I bought the Brinkley book. tx and fed pharmacy and drug law.
I have Brinkley/Cacciatore 8th edition The Guide to Texas and Federal Pharmacy and Drug Law. I paid $159 for this text. It has a lot of highlighting and writing in it.
I used this book alone and passed the MPJE. It really did help a lot.
