Well, if you happen to be using Website Payments Pro UK or Canada as opposed to US, they don't bother mentioning they don't support AmEx and Discover until you call them and ask why the payments aren't going through.
This is not true when using Paypal Payflow Pro or Website Payments Pro for your merchant account.
