yeah theres some guys that do it for a living on BO that are very good, and send international at cost ($7-$10) pm me if you want a few recommendations...
Firehand sports cards hands down best around. Free shipping to us aussies and hitless packs to anyone who misses out.
They only ship international every fortnight but if you want one shipped express just fix them up. They do BGS subs and sell on ebay for you if you want to sell your hits (small fee)
They are live everyday on breakers.tv.
Ken from K2sportscards is also a great guy who gives from his pc for hitless teams.
I use mojobreak, it's like $6 for international post and I get mine within 2 weeks.
Using COMC, I guess the base cards @ $1 per unit v the international cost would almost break even as to the method chosen for delivery?
