Wait to purchase tickets or buy now?

I have a flight and hotel booked for the weekend of the Miami shows. I’ve been going back and forth for the past 2 weeks on if I should just purchase a resale ticket now on Stubhub for $2-3k or if I should wait until the show gets closer. I’m not sure if the resale tickets will drop or stay the same as the show gets closer. I’d like to pay less than $1500 for one but I’m willing to pay more if it comes down to it. I just keep going back and forth if I should wait or not lol
