I have 50% discount from Grubhub (I am a driver) but I don’t see it reflected in my total. Please help

Thank you!, but this answer was not helpful. The reason why I posted a question is because the answers in here don't provide a solution to the problem :(

Solution is .... you MUST enter the TT program  THRU  the grubhub site using their link to the TT program so that the program will give you the discount.  

Thank you!. Unfortunately that doesn't work either :(.
