Great post. As an aside the cheapest place I ever found to buy a book was the country India. Books at literally a fraction of the price you would pay in Europe or the USA...
Thanks! Once I'm done accommodating more regions into the tool, it should also allow filters for international shipping which will ofcourse have much higher delivery times but as you say will often be significantly cheaper overall.
You might have to account for toll fees since the price does not represent the final amount of money one has to pay.
Currently it's only accurate in the USA, I'm working on implementing more regions so that it is completely accurate around the world
