KCON LA 2026 merch

Hey! I’m going to my first KCON LA and I’ll be attending Day 1. I was wondering if they’ll be selling official group merch at the convention. I’m mainly hoping to buy TREASURE merch, but I’m not sure if every performing group usually has official merch available. If anyone has been to previous KCONs, I’d love to hear what it’s been like so I know how much money to save. Thanks!
