After the show — trades and ISOs that don’t get buried in the event page
Concert tees, pins, kandi, signs, and “ISO this size” posts spike around festivals, tours, and big matches. ISO App fits trade, gift, and clear wanted posts — with optional event context and hashtags so the same crowd can find you days later.
Trade & gift are first-class
Use the Trade feed or mark a giveaway — barter and PLUR-style gifting are normal here, not edge cases.
Event context on the post
Name the show, tour, or match in Context (e.g. “Gorge weekend”, “World Cup watch party”) and tag #trade, #merch, or your event hashtag.
Local pickup + shipped offers
Check “Open to shipped offers” on your post if you’ll consider postage — you and the other person arrange it yourselves; ISO does not ship or hold payment.
