STK International

Only sells within the U.S. Amazing...

try this site, it costs around $NZ180 per annum for your own physical address in the US and they forward the mail on to where ever you like for very cheap rate. I've been using them for about 3 years, they are really good. They will declare minimum prices for customs(gst), hold packages and send in bulk whenever you want. Check it out

Yea, really good advice. A US address will open up all sorts of opportunities, and there a quite a few forwarding companies out there that offer this service.
