Can I pay using AMEX?
Yes - but currently ONLY for payments in EUR.
If you wish to pay directly via an AMEX card, you must pay in EUR.
If you choose to pay in USD, payment by AMEX is not available to you directly. (i.e. AMEX will NOT appear in the dropdown menu)
If you wish to pay in USD via an AMEX card, you can do this by selecting the Paypal payment option.
