The cost of a ticket is the price of a copy of the book at Octavia. You trade the ticket for the book at the signing. Unfortunately, the store’s website indicates that Alton will only be signing books purchased from the store. I bought my ticket yesterday, and it came to just over $40 with in-store pickup. Also, for those who want pictures with AB, keep in mind his no-camera-phone policy (third paragraph from the bottom) and bring a real camera.
See you there!
