“Custom/Low Serial number” option required for earlybird deliveries?09/26/2017 Solved2.25K views09/26/2017 holt (anonymous) 09/26/2017 0 Comments I’m a little late to the game here so not sure if early bird is still available. If so, do I have to select the Custom/Low Serial number option? 1 AnswerActiveNewestOldest admin Posted 09/26/2017 0 Comments Yes early bird is still available! The low serial only puts you towards the front of the line in the early bird round – not required to be in the early bird round. Login
