Gamebore actually has a office/distributor here in the states...I emailed them a ways back and never got any response. Last week I contacted a shop in the UK and this was their reply.
"Please can I advise you to contact Gambore in the US 281-794-5788 shipping to get them to your local air port and no further is going to be around £1000 depending on quantity. Ordering over a 1000 cartridges will give you a cost per carton (250) of £86.13. I believe contacting the Gamebore rep in the US should provide a cheaper alternative transport.
