I charge everything on my Amex platinum. I got taken for $6,000 when I paid with Paypal and they would not help me so I called Amex and got my money back in 5 minutes. Screw Paypal. I will only call Amex in the future with any problems.
P.S. I use my Amex exclusively. If a place doesn't accept it then I do not shop there! I am a loyal Amex customer.
