I guess you should see it as a search game
"search the right items within 5 minutes".
My J-Pop collection so far:
Ayumi Hamasaki - GUILTY [CD+DVD+Photobook] First Press Japan version
Ayumi Hamasaki - Mirrorcle World [CD+DVD] Long Sleeve Hong Kong version*
Koda Kumi - Kingdom [CD+2DVD] First Press Japan version
Koda Kumi - LOVE&HONEY [CD-only] Japan version*
Namie Amuro - CAN'T SLEEP, CAN'T EAT, I'M SICK [CD-only] Japan version*
*= I ordered them but YesAsia hasn't shipped them yet.
