Also, dealing with AMEX screws up a lot of forms.

15 numbers, 4 then 6 then 5. Yes, only 3 groups. And the CVV2/CVC2/CID is on the front and four digits, not three.

I wonder if this has any thing to do with why amex was so infrequently an available payment option online for so long...

I doubt it. A more probable reason is the higher transaction fee charged by Amex (3.5% compared to 2%).
