I just got a 27" monitor from Korea to the Midwest in 3 days if that puts anything into perspective.
But you are talking "western" country to "western" country .... customs between China and U.S. in particular is a tough business, I know because my in-laws ship simple over the counter medicine/vitamin supplements to their chinese friends and even those get thoroughly inspected very frequently, they'll get to chinese customs and then sit there for ages.... sad but true.
I have had en ebay item shipped from a company in Hong Kong to the Eastern US in under 6 days.In fact,my prior job used to do plenty of mail orders from mainland China to the US and they usually took less than 6-7 business days.
