I ordered a drive belt for my F800 last year from MAX. Shipping was going to be 43 dollars for a 500 dollar belt In the comments I asked if they could call me about the shipping.
I got a phone call that day and I was told that the way the belt was packaged was in a large box which is where my shipping costs were coming in. Size not weight. So I asked them to remove it from the original box and roll it up into a smaller box. They said that BMW didn't recommend folding it. I told them it didn't matter I was going to pack it in my luggage as a spare part anyway.
They rolled it up into a box for me and saved me 30 dollars in shipping.
