The phrase "shocked" doesn't occur in the post, so I'm not sure where that term comes from. He does say that the quoted figure is more expensive than he hoped for, which is reasonable, since he goes on to present a number of quick calculations suggesting he can't justify purchasing them at that price.
This is a blog about how a citizen in a developed country is "shocked" at the concept that other people should be paid a fair wage even if - gasp - they're Chinese.
