Soooooooo.... a PS3 sold for U$ 350,00 in the US arrives in Brazil costing U$ 700,00 at least! A damn shame, I know. The most bizarre part of it is that you can buy imported PS3 consoles in Brazil cheaper than the ones Sony will be selling officially, so it's really hard to know why they are even selling it for that price. My guess is they'll be focusing more on the games market, since there is no piracy going on as of yet.
And yes, you could travel to the US, buy your damn console and bring it here paying no taxes, supposing you stay inside the taxation free limit. Shipping it might be risky if you don't voluntarilly declare its value for taxation purposes, specially for eletronics, since it might get caught and you'd be forced to pay twice the taxes plus fine.
So yeah, its very expensive to buy technology in Brazil...
Mainly because of taxes. Adding it all up, import taxes alone reach about 100% the price of the product. You put profit on top of it and the cost might go up to 200% the original cost for a specific product.
