Ok, WORLDLY people, what's up with this ebay auction (China Beijing 2008 Olympics)?

I have a friend who was in China last week. He said he picked up 2 sets of coins like this (I will wait and see them later in the week when he returns).
This is the auction link he sent me to show me what the coins are....
So, I look and the price seems low (even in AU$ converted to US$). Then I look at the SHIPPING!
Fee avoidance? Should the right price be about what the buy price+shipping price be?
I've heard these are limited mintage. Hard to get? Easy to get? Did my friend get "shanghied"?
Anyone know what the coins are made of?
Thanks for any info.

I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment

My friend knows nothing about coins and I know nothing about these so I figured it was worth asking
