as a retailer, I'd like to see an AMEX black card, or amex period. It's the best card for us to see. 99.99% of my customers don't do a charge back or file a stolen card report.

Oh yea, and for a 2500 fee to use the black card, is cheap for any black card holder. After all, anything you use that card for, business wise, is a tax write off.
