Other than the mainboard and CPU heatsink which couldn't be shipped directly, every other item were shipped directly. I spent a total of USD17.47 to ship the mainboard and heatsink over. As you can see, the savings is easily into the hundreds and more than cover any fees required to ship an item for RMA. Heck, the savings can even cover the cost of a major item such a mid-range graphics card.
