We are a Canadian company based in Vancouver, so if you are buying our products as a Canadian resident, you will be responsible for paying all applicable value added taxes (such as HST or GST) on top of the amount that will be credited to your account.
If you are buying from the EU and do not have the VAT number, you will have to pay VAT tax on every purchase you make. If you have a valid VAT number, you must provide it in Your Account > Billing Information, using Reverse Charge Mechanism to account for the EU VAT on the transactions. For more information on EU VAT, please see this article here.
In all other cases, no taxes will be applicable to your purchase.
