Important Notice Regarding Changes in USA Policy to De Minimis Shipments: Due to changes made by the US government and the removal of the De Minimis exemptions for American customers, many postal services worldwide (including Canada Post) have suspended small package shipments to the USA until such time that they can fully comply with the reporting and administration requirements the change imposes. As a result, we are unable to use postal methods to ship orders until further notice. Orders can be shipped via FedEx only, and all duties, tariffs, brokerage and clearance charges will be covered by the shipping fee charged.
