When you sign up, you can check your 20% fee discount in your account settings. Can you see the message '20% commission'? Yes, then, it is correct.
Note: If it shows “10%”, "5" or no message appears, that means the code wasn’t applied. You cannot add it later, so it's important to enter it during sign-up.
