#2 Fill the Scotiabank Arena
WWE has been going through difficulties in case of ticket sales for several events from the past couple of months. WWE house shows are the most affected ones. Even pay-per-view events are sometimes not sold out till the last minute these days.
According to a recent report, WWE is offering a "Buy 3 Get 1 Free" promotion on tickets to fans for the post SummerSlam shows in Canada.
DX participating at the biggest party of the summer will definitely spark some interest among the fans, and push them to attend the show. Moreover, since they are a special attraction for Canadian fans, more of them will be interested in the show.
RAW Reunion was a sold-out show, where fans showed the nostalgia they had for the former tag team champions. It is a team well-loved by the fans, with its special charisma that just attracts the fan-base. In addition, Shawn Michaels wrestling is a very rare sight in this era, so Canadians will consider it a must-see show (despite 'the incident' in Montreal all those years back).
