Hiya Chibiusa,
I bought something on YJ which ended on Nov. 11th 
and I'm still waiting for it.  I paid immediately 
too!  I also read a little bit about the 
service's shipping policy (a month after the 
auction ended!), and I learned that they don't 
necessarily ship things automatically.  You may 
need to fill out their "ship my stuff now" form 
due to the high number of requests sellers have 
had in the past with regards to combined shipping 
of multiple auctions.

I filled this form out exactly one month after 
the auction ended only to have them reply that 
the cel has not been inventoried in their 
stockroom yet (and I was told not to worry, the 
seller is reliable).  I have instructions to 
check back in a week (today).  This is kinda 
annoying, but if I get my cel in the end 
(relatively soon) I'll be happy.  I believe the 
deputy service is reliable, although it is my 
first time using one.  I won't publicly bash 
either  ^__^  unless my cel never arrives... then 
that's all I'll do!  >:P

Ja ne,
Ghosty

PS- feel free to email me if you have any 
questions  ^__^
