Why so slow?

I keep checking the status on the goods I ordered from Gmarket, I'm still waiting for my Shinhwa cd..
I wonder why it's so slow.. I want my goods and I want it now :P
The Korean post service within Korea should be faster, I mean the cd was released yesterday ^w^

I ordered a scarf, a bag, mobilephone accessories, earrings and the Shinhwa cd...
anyway it should be shipped out on Saturday or Monday, so it should be here within next week or so.
