Again, when we're talking about watch prices, we don't add shipping. Shipping costs vary from location to location and shipping mode (airmail or express, direct or triangle). If you're in China, you even get free shipping (last time I checked).
The PAM382 Bronzo uses a P.9000 Superclone movement. The PAM968 Brownzo will most likely use an A7750 movement with P.9010 decorative plates as this has a display caseback and aesthetics will come first (the P.9000 looks different from the P.9010, leaving aside the difference in balance wheel location). That's why I think the price will be closer to the PAM671 than the PAM382. Now if it had a closed caseback, the factories would probably use the Superclone P.9000 to justify pricing it closer to the PAM382. Anyway, we're all just speculating here in the peanut gallery. Let's see when the watch is finally released.
5 years ago when I was in Shenzhen, we get free shipping by sf express and can pay upon receiving the package.
