I think people in your region, LGW, get royally screwed.With all honesty, I do not know why.
I understand that import taxes may anything seem more expensive (or even cheaper)... but when that is removed, the same things should cost the same. Prices of most GW models are 40% more expensive in Australia and New Zeland. Yet, models from most other manufacturers are priced equally in different parts of the world.
I don't buy products from companies in the UK not because the British Pound to US Dollar conversion makes things more expensive; it is not the manufacturer's fault that the Pound is stronger or weaker, same price for everyone. I don't buy stuff that is located in the UK because the shipping from the UK is a killer.
But with GW is weird... the product is already in the region. It was transported in bulk (read, WAY cheaper than a small airmail package) and STILL the product is prohibitively expensive. To make matters worse, GW cracked down on web stores that were Australia-Region friendly (UK prices with reasonable/cheap shipping).
Your best bet... beg Laney or another chap for help. You will get none from the big stores.
