Hi there, I am designing a shopping cart for my company, and I have a dilemma: in a physical shop, sales taxes are calculated based on local ( state/province and city ) rates. online, Amazon calculates taxes based on amazon site you are connected to ( amazon.com applies US rates and amazon.ca applies Canadian rates). in other hand, Apple online store applies taxes of the state or province you are shopping from.
Here is the thing: let's say I am shopping from Canada, but I want both billing and shipping address to be in US. what tax will be applied? ( canadian? or US?).
thanks for the help
