Cheap digital print in USA that ships worldwide

[Zappa]

Hey there,

Did a bit of searching and couldnt find an answer..

I print around 500 A2 posters a week here in Australia - the price is around $440 (US) delivered for that quantity,

I've noticed T-shirts are quite cheap to print in the US,

Does anyone know of a poster printing place in the US that would ship to Australia for a cheaper price then what im getting at the moment ?

Thanks!

or even if you list your cheapest prices in the US and I can ask them if they'll ship to Oz?
