In the end, it's best to just not worry about what people are paying for goods in other countries because there is nothing you can do about it anyway.
Im getting education prices when I goto the US (im a UK resident), on the 2.2Ghz MacBook with a Mini-DVI Adapter for about $1,280 inc tax aka £640. It'd be £793.13 in the UK on an education deal.
£150 difference.
My flight is only £280.
Now technically, I believe customs rules dictate you have to declare your purchases etc.. Which may well involve added taxes.
Either way, its a decent amount of cash if you're actually in the country, if you were trying to ship it in - i'd say don't bother with the hassle.
