It also never made sense that the U.S. market seems cheaper than even the Asia market.
It makes total sense. It's all about volume and competition. If I, as a retailer or big factory PC maker promise AMD or Intel to buy 1,000,000 units during the next 12 months, then I can demand get those units cheaper than another guy who can only promise to move 50,000 units.
And if I as a retailer, want the sell, I need to price these units the same or lower than NewEgg or Walmart - who is doing the same with me.
This is why me, as an independent custom PC builder, tell my clients I can't beat Dell or HP in prices. I can't buy 1 million motherboards, 1 million CPUs, 1 million cases, 1 million sticks of RAM, 1 million power supplies. I lucky if my client wants 3 computers. Typically, I build one at a time.
Another problem (perhaps a really big problem) with prices in some parts of the world is the costs for all the bribes and lining of pockets needed to get a pallet of products from point A to point B intact and in any sort of timely manner.
Bribes are probably not a problem once that pallet gets to the docks in NZ or Australia, or England. But they may have been a problem all the way up to getting that pallet loaded on to the cargo ship heading to those countries.
