Although our online payment interface does not accept AmericanExpress,
we can offer this workaround: use PayPal.
PayPal (www.PayPal.com)
is a widely used and trusted tool for exchanging funds through the
internet. If you will create a PayPal account, you can attach an
AMEX account to your PayPal account. You can then use your PayPal
account to draw on your AMEX account to send payment to us.
If you wish to use PayPal to pay us, please contact us first. We'll
send you a PayPal 'Request For Funds.' You will then receive an
email message which will help you complete your payment.
