When I travel to Shanghai, I ordered a Western Digital Purple Disk. 4TB SATA6Gb / s 64M Monitoring Hard Drive (WD40EJRX).
I paid RMB705, including free shipping. Now the price is dropped to RMB659.
The similar hard disk on newegg.ca is about CA$238.
Open the box. It is a plastic container.
Remove the plastic container, the hard disk is inside of the the anti-static bag.
