With ticket sales lagging compared to previous years, WWE is once again offering up to 20% discount on select tickets to celebrate 20 years of CM Punk using the code PUNK20.

Tickets on sale include Smackdown, non-televised live events, and the Worlds Collide show, with events from August 14 through October 30.

These 22 events will all feature the WWE champion on them, with Punk resuming his full-time schedule following a post-WrestleMania sabbatical.

While Punk is not officially advertised for Worlds Collide yet, the champ is expected to appear considering the show will be at the Allstate Arena in Rosemont, Illinois.

Worlds Collide, which will feature WWE and AAA stars, collides with AEW All Out on the same day at the same time, with All Out held in the neighboring Hoffman Estates. Currently, Worlds Collide is outdrawing All Out in terms of ticket sales.
