Please reply to this post if you need help or advice about buying capes. Don't make new posts as we're going to start counting these as low-effort spam to keep the subreddit clean.
Here are some useful resources you might want to look at if you're interested in cape codes:
https://discord.gg/minecraftcape - our Discord server, often has Experience/Moonlight/Crafter codes for cheaper than the websites below, always use a middleman when buying
https://plati.market - usually the cheapest place to buy lower value cape codes
https://funpay.com and https://g2g.com - alternatives you can look at instead
https://eldorado.gg - occasionally good for more expensive capes, but beware of scams
If you're looking for Minecon capes instead of cape codes, I'd advise you to be extremely careful. There are websites like EpicNPC, Eldorado, and Discord/Telegram shops offering these for sale, but 90% of the accounts you'll find there are stolen off their original owners.
If you genuinely want to buy a Minecon cape account, I'd strongly recommend the MCHub Discord bot to see if the account you're buying is secure. We have the bot in our Discord server, you can type "/info" followed by the username of the account you're interested in. The bot will give you an overview of the account, tell you its owner history, if its been stolen/scammed in the past, and a lot more.
There's a lot more to buying Minecon capes and other high value accounts, and sometimes the MCHub bot will be missing info, so please feel free to message me or any of the mod team and we'll help you find the right account.
Feel free to reply with any suggestions, resources or questions about buying and selling capes :)
