For international (non-EU) card payments, the currency in which the payment is taken can change with some exchange rate variation implications. This can mean that the amount deducted from your card by the card company may vary slightly than the invoiced amount and is not an additional charge levied by us.
These should not be excessive but if you think they are, then please contact our support center and we will look into it further for you.
In some instances we will have to use a third party provider in order to complete card transactions who may add a small charge. Naturally we would prefer not to do this but the current climate around dealing with cannabis seeds means it cannot be avoided currently.
Please read this blog article for more details of why we currently have to do this.
