A few years ago, there was a story about engines for Vauxhalls (IIRC) being made in Australia, and shipped to the UK. I couldn't believe this was cost effective ... however, one of my customers worked in shipping, and said that for very large quantities (10,000+) booked well in advance, and with a properly manifested ship (i.e. with something to leave the destination port full with) then cost per unit could be quite small. Factor in exchange rates and it can be cheaper.
Although I still can't understand why lamb is such an expensive meat, when the fields near me are littered with the things ... and why from New Zealand ....
