vPost calculate shipping cost by the size and weight. You can use their online calculator to find out the cost. Just put Amazon box size to 1.2 to 1.5 times the size of the book, but with 10cm as the box's height.
It's important to note that Amazon might ship your books in two boxes instead of one. In this case, it might be more costly if you're going by vPost. There's no way to know in advance.
For Amazon shipping charges, it's going to be US$5 + $10 for the box and two books respectively, excluding the cost of the books themselves.
You will want to check out Book Depository which might be cheaper if you're not getting a lot of books. Their shipping charges are calculated into the book's price in advance.
