Nikon Guide to SLR photography delivered for $3

If you are a Nikon fanboy, you can't pass up on this deal! For just $3, you can get the Nikon School: Guide Book to Digital SLR Photography. This is sold by PhotoWorld on Amazon for $3 with free shipping and handling. This is a 75-page booklet in paperback.

As you can expect from its size, this is not a comprehensive and in-depth book, so if you are already an expert, you can probably write one like this.
