You can appoint an agent to deal with customs for you via Pos Malaysia. They'll send a form for you to fill up if your item is detained. Fax the form back together with an invoice (which you can get from the seller). You'll need to pay the custom fees (sales tax etc) + the extra charges for appointing an agent (around RM40) and if you prefer, you can have Pos Malaysia deliver the item to your address for an additional fee or collect it at the nearest post office. If they're shipping it to your adress, you can pay them by cash or by bank draft. They'll call to let you know the amount owed once you've submitted your form and invoice. It's pretty simple.
