Sales taxes in Canada would probably match the US price and maybe even surpass it. In quebec for example, here's the total for the price you posted:
$2500 Your posted Machine Student Price in Canada Before Tax adding the taxes
+ $125.00 GST/TPS (tax)
+ $196.88 TVQ (tax)
=
$2,821.88 CAD (Total Price with taxes that have been calculated and added already, numbers based on taxes in Quebec, taxes vary from province to province in canada)
Now, let's convert that total price that includes the tax $2,821.88 CAD to USD.
$2,821.88 CAD = 2,248.06 USD (February 25th 2009 exchange rate @ 11:05PM EST)
USA Price $2300 USD - Canadian Price with tax that has been converted to USD 2,248.06 USD is = $2300 USD - $2,248.06 USD = $51.94 USD
In conclusion the Canadian Price is discounted at $51.94 USD
Not sure what kind of sales tax you have in the US, it could probably make a difference in the calculations.
