It’s like lets say this individual lives in a state with no sales tax like Delaware (US) purchasing stuff from a seller living in Fukuoka (Japan), the value of this item is ¥30,000 ($189.50) while the same being sold in America is jacked up in price at around $349.99 MSRP retail. The reason why they bought it from abroad is simple: its cheaper at face value, with a catch though: de minimis has been rescinded in the US.
