hello,
use e one in oregon, as it's a tax-free state..california has got sales tax of about 5%, if i remember correctly.
shipping charges will be as follows:
a. vPOSTUSA Shipping Charges
Category 1. Others
$12.40 + $8.60 per kg thereafter
(Based on Volumetric weight1 or Actual weight, whichever is higher.)
Category 2. Magazine
Using Magazine Prepayment Service
for vpost japan, i think yes you can, though i have not ordered anything from japan as yet myself..
and FYI, Coach does not ship to vpost usa address..u have to use agent services like comgateway, bordelinex etc..depending on which sites you order from, generally online prices are cheaper compared to retail prices in SG..a very good example will be Forever 21.
