I sell one of a kind items so a count down limit is very important. without this option I run the risk of multi-selling a single item. It Sounded perfect from the market place description. I read all the reviews before purchasing and also tried it out privately on my site before realizing that it will not count down. I even bought the front end manager thinking that was what I needed. The part that does mention this major limitation is buried on the documentation page so you really have to look for it. I'm disappointed and hope that its possible for an upgrade that could include this option....if so, it would be a really great add-on!
