This company (Pure Formulas) has not been registered in the Import-One-Stop-Shop (IOSS) as other US suppliers do, so you cannot choose among delivery companies in your country if abroad. Consequently, along with taxes the sum total here might be about $10 above than the usual one after delivery. Thus, they keep their business running disregarding their customers' interests.
Tip for consumers: Generally, it's acceptable, but not good due to the lacking Import-One-Stop-Shop (IOSS) registration, which other US suppliers have. So you cannot choose among your local delivery companies that could offer either better or even worse services.
