Buy bitcoins with my regular AMEX (american express card) I can not find any website or service to buy bitcoins with my AMEX.
www.bctquick.com does not work aymore ? (webpage inactive)

any advise ?
You can try virwox.com but it will also depend on the country that you choose for sign up. I know that when you use Germany as the country for sign up, you can pay with AMEX but you will have to covert to SLL first before you can get the bitcoins. I hope this helps eventhough you asked this question long ago!!
