WiseGuys Suggests: If a presale passcode is not working – verify that the pre-sale is still valid: you could be looking at a very old post, secondly keep in mind that there might be more than one pre-sale happening – when there are a few boxes where presale codes can be keyed in you may need to try a couple of combinations to find the winning combination.
