<p>The Rocket Review Revolution, and Grammatix have been discontinued and they are very expensive on amazon. (RR is more than 1k on amazon)</p>
<p>Is there any place to buy these books besides amazon? I tired searching on ebay and I got no results. Can someone offer me some alternative if I cant buy any of these books for cheap?</p>
<p>Edit: I found Dr. Chungs I looked at the Canadian Amazon site before..</p>
