Yes, well, sometimes. My wife used to shop there a lot. Some items 'came' from the US, which were little more than headshops and small warehouses, but shipping was much faster. Still, many items shipped directly from China to your mailbox.
What feels really gross is that they could ship a trinket from China to your door for less money than it would cost me to send it to someone in my own state.
Yeah China Post. It's a combination of factors, including something called the UPU, de minimis, and subsidies on both sides. The USPS loses money on every item sent.
