I’ve paid for the sample last week with my CC. So I guess they will take CC for the actual order as well.
But they do charge a fee. I think it was around 2.8%

if you use a credit card you will not only be charged a 2.8% fee by alibaba.com but also and “international transaction fee” of 3% by your bank. Thats not counting the interest on your credit card you will have to pay because of the order too
