(The strict legal words may be slightly different but the general idea is like this.) For example, you will need to pay tax for purchase from Amazon.com if the goods is shipped to Kansas, Kentucky, New York, North Dakota, or Washington states. But, since US has so many states, most of the times, the vendor is outside your state and therefore you don't need to pay tax.

For Canada, no matter what, you will need to pay GST. And if the vendor's province has HST (like NS, NB and NL), you will have to pay the full HST amount no matter where you are in Canada. For PST though, the idea is similar to that of the US (US does not have federal sale tax like GST anyway). For example, I once bought some thing online from a vendor located in BC (I am in Ontario) and I didn't need to pay any PST. But, since we only have few provinces and the online businesses are concentrated in only few of them (most probably in ON), you will have a very big chance to pay PST.更多精彩文章及讨论，请光临枫下论坛 rolia.net
