I believe this fits in this thread.
I'm on the phone now to downgrade a Sapphire Preferred to a Freedom.
The rep gave me two choices, I can get a Freedom Visa Signature or non Signature.
I played innocent and asked, what's the difference between those two?
He answered, they're the same thing, just with the Signature card you'll have to sign when you'll make a purchase and the non Signature you won't have to sign
Ha ha
