There are three reasons why you may be getting the error that your code is invalid.
- You might be mistyping it; the code is case sensitive and needs to be exactly correct. Please double check it is typed properly.
- The coupon only applies to new AdWords signups, so you are not able to apply it to pre-existing accounts that you may already have obtained with Google.
- The code you were given may genuinely be a bad code. In which case, we were given a bad code from Google and you would need to contact Google AdWords so they may manually credit your account the $50 and bypass the code altogether.
