It is my understanding when you placed an order 
with Taro, the cel is unlisted immediately so 
nobody else can see it.  Therefore, I don't think 
you didn't get any response means the cels are 
sold.  Taro may be busy or having technical 
issue.  I noticed today that some of the cels are 
mis-placed under the wrong titles.  

I usually get a very quick response, but I 
haven't not heard back from them for an order I 
placed very recently.

I would suggest that you wait a few days and then 
send them an email to follow up.
