Expensive Electronics

I'm somewhat curious as to why electronics cost so much in Chile. Most things in Chile are priced relatively the same to the United States perhaps a little less with fruits and vegetables being definitely cheaper. The exception to this is electronics which often cost twice as much as they do in the United States (for example to buy a Nintendo wii here would cost close to 400 dollars. People say that this is because they ship all the electronics from Japan and China and that they are long ways away from those countries. Even so electronics are lot more expensive then it seems like it should be. For example, I could buy a wii in United States for 250 and ship it down here for 50 dollars ... so where is the other 100 dollars going? Part of it is that in Chile the taxes are included in the price so the 400 includes an 11% tax and in the United States its added afterwards but even with that factored in things seem like they should be cheaper. When the family of another volunteer visited them in Antofagasta, their host family arranged for the volunteer's family to buy a laptop in the United States and bring it down with them, because it was so much cheaper to repay the volunteer's family for the computer then it was to purchase it in Chile.
