They carry items to be release (pre-release items) 2 months ahead, but you'll have to apply for an international account and some items will not be shipped to Asia (ie Hong Kong, Japan...etc.) I would check them out, but if you're looking for older releases, keep an eye out for re-releases of previous items.
HOPE THIS HELPS, and good luck with your search....
