Silly question: ISBN for Grammatix?

<p>This is probably a ridiculous question, but I can't find the "Grammatix" book everyone keeps talking about. The only results that come up on Amazon are RocketReview, Maximum SAT, Gruber's, PR, and Kaplan. Am I looking for the wrong book? Can someone give me an ISBN? Is it not a book at all? I'm totally lost here. :)</p>

<p><a href="http://www.acethesat.com%5B/url%5D"&gt;www.acethesat.com&lt;/a> has it</p>

<p>it is not sold by amazon for certain reasons i forgot</p>

<p>Well that kinda stinks. Thanks for the link, but I don't want to sign up for that site. Can anyone give me an ISBN?</p>

<p>its not sold by amazon because if it was then you wouldn't be able to get the money back guarantee if you are not happy with it.</p>

<p>Right, so does anyone have an ISBN? I'm not buying a new copy, so I need to do a search for a used one.</p>

<p>There is no ISBN because it is an e-book. You can only get it from that site.</p>

<p>you wont find one, but if you really need the ISBN email mike: <a href="mailto:mbarrett@grammatix.com">mbarrett@grammatix.com</a></p>

<p>NOW we're getting somewhere. Thank you! Everyone always just calls it "the Grammatix book," so I didn't realize it was just an on-line thing.</p>

<p>yeh but i doubt an ISBN exists and i doubt that it is popular enough for you to find a used copy.</p>
