Tickets to a June 26 punk rock show in St. Petersburg will cost $18 for people who are vaccinated against COVID-19 — and $999.99 for those who aren’t. Fans of Teenage Bottlerocket, MakeWar and Rutterkin will have to show proof of vaccination to get the steep discount. “If you do not care about the discount, tickets are available for a flat rate of $999.99,” the concert promoter said.
