First off, like previous years, Apple will limit customers to purchasing only two new iPhones per day and you can only buy two per store reservation.

On the big day, Apple will once again close normal Genius Bar appointment services to dedicate as many people as possible, about 50% of specialists and Geniuses, to iPhone sales. Other initiatives like Personal Training will also be shut down for the launch period.

At about 6 AM, queuing customers will be split into two new lines for reservations and new buyers (or in Apple parlance, customers ‘ready to reserve’). There will also be some form of food and drink given out to keep the crowd happy.

The doors will open early at 8 AM for iPhone sales. Apple will begin allocating reservations for customers that need them about fifteen minutes before doors open. Customers can leave their queue and rejoin at their reservation time. Customers with wait times shorter than two hours will be encouraged to stay and wait as they may be able to be seen faster than the estimate.

After picking up the phone in the store, at purchase customers will be informed about the different ways they can buy their new iPhone 6s. This includes details about Apple’s new iPhone Upgrade Program, upgrade eligibility and recycling options. After the purchase is processed, customers will be sent on their way to enjoy their new iPhones.

If Apple Stores do not have stock during the launch weekend and beyond, Apple Store staff will be encouraged to get customers to place orders online or tell them to try and make a reservation for a future date. Reservations can be made online from 8am every day.

And that’s it — how Apple customers can get their hands on the new iPhone 6s and 6s Plus at retail. Preorders for the phone started on Friday and it’s already on pace for a record debut; almost all of these orders should be fulfilled on launch day whilst stock is still available. The new phones goes on sale on September 25th.
