Around 2 weeks. It seems that they ship the package first to some depo in Netherlands and from there it gets shipped to your actual location.

I bought twice directly from keychron.com (I'm in Lithuania) and the keyboards were delivered directly to the door basically (no additional import taxes, customs inspections or anything). Shipping cost though is 31 USD per keyboard/numpad. Doesn't seem to matter what kind of board you buy, it's always 31 USD per one keyboard (or numpad in case of Q0 or Q0 Plus).
