I too have not been able to cross grade. Put my first ticket (Case 120523) in 12/31/2012. My code still doesn't work. Oh, and I have had no response other than an automated "received your ticket" notification. Also - my error message says, ***No reduction currently available, please see the coupon restrictions*** even the code is supposed to be good through 1/7/2013 BUT... if i change a letter in the discount code the error message says, " Invalid Coupon Code"
