Just curious, do those prices include the VAT ...
Yes, the prices include taxes. I forgot to mention that.
According to the salesman, if I wanted to buy the ST220 tax free for exportation purposes, the price will be reduced by approximately 22%. Of course, one must add local sales taxes (here in Montreal we have the federal and the provincial taxes which add up to 15.6%). Then you have to add the transportation cost and probably additional customs fees.
