I'm going to keep directing newbies to these 
links so they'll find the information they need 
AND they won't clog up on this particular message 
board.

Here's a reply I sent to another person before...

The Yahoo! Japan forum can be found here:

http://pub41.ezboard.com/fanimecelsforumfrm3

This forum is better suited for you, since it 
focuses primarily on Yahoo! Japan.  They will 
probably also answer questions you haven't 
thought of yet.

Here is also an FAQ/information page that might 
assist you as well:

o.html

And please understand that I'm not trying to give 
you the run-around; visit these links and they 
WILL HELP YOU.  Regulars on this board try to 
steer newbies to these links so the Animanga 
forum doesn't get too cluttered with YJ questions.

But in a short reply to your question, I would 
need to view the specific Japanese text first, 
since that rough translation doesn't help much at 
all.  It may be a dutch auction of 20 of the same 
item.  Do you have a link to the auction?
