Business Law & The Legal Environment by Anderson, Fox, and Twomey West's Business Law by Clarkson, Miller, and Jentz These are two I have been using. Either one will suffice for the DANTES exam by itself. I picked them both up used for under $5 combined. The first one mentioned is easier to read if you don't like to be put to sleep, but they are both 1000+ page books. Of course, you don't need to read everything in the books, but I'm just giving you an idea of the weight (pun) of the subject. I'll be taking this one next month, so I'll post my experience then.
