What it costs delivered
These are the totals for this one product on its own: the shop's price, its postage to that country, and what the border adds. One item rarely clears a shop's free-shipping line, so postage is most of the difference here — a whole routine spreads the same postage over six steps.

Under the ₱10,000 threshold there is no duty and no VAT. A courier may still bill an import processing charge, which nuvy does not size.
The cheapest shop changes at the border. BuyBeautyKorea has the lower shelf price, but delivered to the United States it is beaten by Stylevana.
Shipping uses published shop rates where available, with nuvy estimates marked separately; the border's share follows the rule on that country's duty page, each read from the customs authority's own document.
