as per you know amazon usually shipped quite a big boxes no matter your stuff is small or big.. i was headache too dealing with amazon.. but what to do you need to check their amazon shipping weight + the item weight before u plan to purchase.. if u shipped just 1 item back to msia ofcoz the shipping fees will be expensive.. try consolidate many many of your purchase to save the cost...

i have 2 customer purchasing lego at amazon from me.. i charge them on the boxes fees too.. but i have combine shipping every week so they safe more on it.
