If you are talking merch sales, see below, if you are just saying Punk had a doper shirt, then that is your opinion.
Rey Mysterio has easily sold 10x more merch than Punk. And I mean I think 10x is LOW. And Jeff Hardy was number 2 or 3 (behind Cena and Rey) for like 5 years, he has also outsold Punk by 5x EASILY. And I literally mean easily. The shirts, the pendants, the arm sleeves, the hats, his action figures, hell they were even selling a Jeff Hardy MASK of his facepaint the last 6 months of his run before he quit.
Punk has had one year of merch sales, his other shirts sold NOTHING.
When have you EVER seen ANYONE in a WWE crowd rock these shirts?

And this new yellow shirt, which Vince shytTED on national television, is nowhere to be seen in audiences in the last month.
His new yellow shirt is outselling cenas look on the site at best sellers bro . Dbry Ryder and punk.
We have no numbers to say how much Jeff sold but they don't usually make multiple shirts for people that are flops. you realize they have a thing called the Internet that people can use to buy shirts too
