True about changing the shipping address, Amazon won't allow you to do it. But 110% wrong to say too bad.
If you had someone at that other address, they could still keep it.
What they can do next time... if you believe you won't be at the first address after it was Ordered. They can cancel the order, you get your money back
and then you can Re-Order with the new address
they should review that no address change for international buyers, I do have 5 diff addresses registered and one of them belongs to the courier I use, there shouldnt be any problem for to do it because they can check my card is not a US issued card is an international card nut anyways I can see where they are coming from with that policy, in the end what i didnt like about that particular vendor was their fcuk off attitude towards me from the beginning. They wouldnt even try to present me some sort of solution or arrangement so had to go straight to amazon and have them fix it
