Presale tickets for this tour were initially sold only in-person at the venue box offices in an event dubbed the Physical World Presale. The purpose of this presale was to try to get the best tickets into the hands of the most dedicated fans and to minimize reseller scalping (and to create a social event).
At the presale, there were merch booths setupset up, selling vinyl, apparel, and accessories, including an exclusive litho listing the presale cities, and an exclusive "In The Physical World" t-shirt with the city name. There were also headphone listening booths setupset up, where fans could listen to "Play The Goddamned Part" and "Ahead of Ourselves".
After the Physical World Presale, the remaining tickets were later released through normal ticketing channels. The original announcement[https://www.nin.com/tickets2018/] reads:
