I wouldn't know because I'm not from the US; always bought them online and had them delivered here.
Sybex has two main learning series: Essentials and Mastering. The first being more focused on exercises and examples for quickly making you productive and the latter is a much more comprehensive book (but also covers the basics). Also Essentials books are about 400 pages long while Mastering don't go below the 1000 pages.

Most of the 2014 version of the books are going to be publised during July, you could tinker around with the programs until then; Autodesk has some tutorials and learning materials available, specially if you're registered as a student.
