The product is supplied by a seller but the person you're actually dealing with is Amazon. If there is any problem, you will deal with Amazon and Amazon will deal with whoever.

However, I suggest that you visit a local video/music store and ask them to order it for you. Some bookstores might do it for you too, like Kinokuniya.

If you buy from Amazon, they will charge you a very steep international shipping rate. Their free shipping only applied for shipping within UK.

Depends what kind of shipping you chose. I'm not sure of the exact price. It may take longer than a month to reach your house, or maybe less.

Just go though the checkout process all the way until it reaches the part where you have to pay with your CC or Paypal. That will be the total amount you have to pay in all. Make sure you have your address right and the country is set to Malaysia.

You won't be charged anything extra later. However, there is a possibility you may get get taxed by the customs, or they may tear open the box, not the wrapping, I mean the actual box with the Friends printed on it and remove the wrapping on the DVDs. These kind of things do happen, just to warn you.

They are the customs. They don't need your permission to open it.

I remember reading about a case where they used pen knives to cut or damage some collector's box for Coca-cola cans. To the collectors, the box was just as important as the cans. But to the customs, a box is a box and they'll have to open it to check it's contents.

They banks will charge you an elevated interest rate and a transaction charge. Both are counted in a percentage of the total amount.
