## Description

Cardume was born from a real pain point: managing group card trades and purchases via WhatsApp is chaotic.<br><br>Who owes what? What was the last trade? How much does each person pay for shipping?<br><br>With Cardume, all of this is organized in one place — within closed groups, based on trust between friends.<br><br>━━ SMART TRADES ━━<br>Register your trades and track the balance with each friend in real time. No mandatory confirmation — because among friends, a friend&#39;s word is their bond. But if you need to dispute, correct, or cancel a trade, you and your friend can do so at any time.<br><br>The best part: Cardume simplifies chain trades. Someone has what you want, you have what someone else wants, someone else has what someone else wants — the app shows you how to resolve everything at once, without losing anyone along the way.<br><br>━━ GROUP ORDERS ━━<br>Want to split the shipping cost of a group purchase? Create an order, each member adds what they want, and the app calculates how much each person owes. Simple as that.<br><br>━━ CLOSED GROUPS ━━<br>No strangers. You join by invitation and only trade with people you already know. The history of trades and orders is recorded for the entire group to follow.<br><br>━━ TCG STORE COUPONS ━━<br>Found a good coupon? Share it with the community. Tired of searching for discounts on Google before every purchase? Cardume gathers and ranks the best TCG store coupons in one place.<br><br>━━ WHO IS IT FOR ━━<br>Players of Magic, Pokémon, One Piece, Lorcana, and any TCG who frequently trade cards and need a reliable way to organize it all.<br><br>Download for free and invite your group.
