SAL isn't the cheapest way, though - it's the second cheapest way. The cheapest way is by SEA, and to me the price difference between SAL and SEA is quite a bit. I send all my items home via SEA, which is the 1.5-2 month option, though one box got home in a week.
Check the post I made under the thread "Shipping Options" or something like that. It was only a few weeks ago so it should be on the main page. In there I explained all the shipping methods, and the details.
