Amazon's shipping is extremely cheap for Japan, but obviously, only if you are buying a handful of items. When you're already paying for 49 items in one order, there should be some kind of bulk order discount, not a shipping charge of 17,750 ($165), especially not when a person living in Japan can send a 7kg* parcel to the US with EMS shipping for 11,200 ($104). Why is Amazon, one of the biggest online sites in Japan, actually charging me 6,550
more for shipping than what Japan Post would charge to ship from person to person? This is an obvious weakness of Amazon's
shipping rates to North America, which go by item, with a 600 base and then 350 per item, but no cutoff or bulk discount. It's silly to keep adding on 350 after a certain point, so where it gets cheaper to ship by weight, they should at least offer that option.
*Assuming each Blu-ray weighs 5oz, meaning 49 weigh 245oz, or 6.95kg
And obviously, this shipping issue with Amazon plays into why they won't ship the trunk set to the USA (and probably not outside of Japan), because they want 17,750 to ship 7kg of Blu-rays ordered as 49 items together, but their system is set up to charge only 950 to ship a 15kg Blu-ray box set because that would be counted as one item.
