WWE has changed the pricing for tickets to Extreme Rules later this month and they're once again being offered as part of a 2-4-1 deal. This is the second time WWE has done this recently and it's actually quite surprising when the PPV has such a strong card!
In the case of Stomping Grounds (which mostly featured rematches from Super ShowDown), WWE ended up giving tickets awat at a local mall in Tacoma, Washington before the show started.
Attendance was also shockingly low as the show only drew 4000 - 45000 fans in an arena built for 18,000 people. WWE clearly doesn't want that to happen with Extreme Rules and pricing tickets like this makes sense until the company is able to regain the trust of fans who have grown bored of the product in recent months.
Extreme Rules features a number of big matches, including WWE Champion Kofi Kingston vs. Samoa Joe and a Winner's Take All Extreme Rules match pitting Universal Champion Seth Rollins and RAW Women's Champion Becky Lynch against Baron Corbin and Lacey Evans.
