FYI when ordering the ppv there's seperate links for each participant, I would assume to track ppv sales for payouts.
If you don't have a favourite grappler/fighter on the card and are just checking it out might I suggest the Dustin Poirier, Gordon Ryan or Gary Tonon links . Both have publicly mentioned they were donating their portions to worthy charities.
Edited to add Tonon to the suggestion list as he's now donating his sales pay as well.
