Arch gets better through the people who use it. Whatever it is - a suggestion, a bug, a price that smells wrong - we read everything.
Feedback & suggestions
Missing a feature you'd use every day? Something confusing or slow? Arch is built from user suggestions - several of its features exist because a collector asked. Tell us what would make it better for how you actually collect.
Wrong or weird data
Spotted a price that can't be right, a card matched to the wrong listing, or a set that won't come up in search? Send a screenshot and the card's set + number - data reports like these have already fixed real bugs.
Partnerships & data
Marketplace, grading service, or store interested in working together? We're always open to conversations that make card prices more transparent.
