Yes, I received today 5.1-newsletter to the email address I entered. The message already appear on the "payment" dialog. The code (I don't know if it is allowed to post it here) is already entered in the "Coupon or Promotional Code" field. I then try it explicit to "Apply". The page refreshes and I get the same message "Sorry, we were unable to validate the Coupon Code you entered.:" in the upper right corner in the calculation.
