The Extreme Rules pay-per-view at Wells Fargo Center in Philadelphia is only 10 days away now, but once again, WWE seems to be having serious problems in selling tickets for a major show.

As pointed out by Ringside News, Wells Fargo Center is offering a bargain 2-for-1 one ticket promotion. Tickets were starting at $27.40 as of Thursday afternoon, and the most expensive were floor seats for only $125.

Wells Fargo Center sits 19,500, but it already seems like there could be a large quantity of empty seats for the event. It's obviously not a good sign if they have to run a two-for-one promotion.

WWE had to run the same promotion for the Stomping Grounds pay-per-view in Tacoma, Washington. Ticket sales were extremely low heading into the event, and fans could get a two-for-one deal for as low as $20.

It was later reported by Bryan Alvarez of Wrestling Observer Radio that WWE was handing out tickets for Stomping Grounds at a mall. He also said there were only about 6,000 fans at the show inside the Tacoma Dome (it sits 23,00), and only 4,000 to 4,500 were "paid" attendance.

And unfortunately for WWE, it seems like they're headed for another pay-per-view show with low ticket sales and attendance. They're simply hoping that the 2-for-1 promotion will lead to more sales between now and next Sunday.

So far, there are six matches confirmed for the Extreme Rules card. Seth Rollins and Becky Lynch will defend the Universal and Raw Women's Championships in a mixed tag match against Lacey Evans and Baron Corbin. The Undertaker and Roman Reigns will also team up against Shane McMahon and Drew McIntyre. Kofi Kingston (WWE Champion), Bayley (SmackDown Women's Champion), Drew Gulak (Cruiserweight Champion) and Daniel Bryan and Rowan (SmackDown Tag Team Champions) will also take part and put their titles on the line.

What This Means

WWE rarely has problems in selling tickets for pay-per-view shows, so it's quite surprising to see them go through this issue in consecutive PPV events. It's obviously a sign that fans are frustrated with the current product and don't have much interest to see these events. WWE has no choice but to sit back and hope that ticket sales will jump up over the next 10 days.
