According to my arithmetic (based on winning bid 
numbers), Usagi's house is handling about 40,000 
YJP auctions per year through their Rinkya arm.

That's about 750 per week.

Think what it must take to keep up with THAT....

(This is assuming that the bid number gets 
incrementd by a winning bid.  If it gets 
incremented by any bid (even a losing one), then 
my arithmetic is a fallacy).
