Hey, I noticed that Amazon has your 2nd Edition of EFAD Up, but it is listing it as a completey separate page and calling it a "Mass-Market Paperback". The page for the original is still up on Amazon and indicates the book is out of stock and not available.
On your site, you should link to the new page and include that link in any promotional material. Also, you should have Amazon make sure that all of the reviews now listed on the old link, carry over to the new link and that the sales ranking is a combined total for both. It looks like people are having a hard time finding the new link. They may keep coming to the old link to see if any are available.
Just a couple of thoughts. I am entering my review at the new link so you have a review going. I'll purchase one of the new ones there to to try and get the ball rolling.
