1. Attach adequate postage to your envelope. One forever US stamp mails 1 oz. Additional ounce stamps are available. If you’re outside of the US, please check with your local post office.
2. Include your user name in the envelope when you trade. It helps other users give you credit/thanks for the successful trade.
3. Follow through. If you need to back out of a trade, communicate that with the other user. If you have problems, contact me or the other mods.
4. Do NOT post full names or addresses when making thank you posts. Protect everyone’s privacy.
5. Be respectful in your communication. You will be banned from the community if you are constantly rude to other users.
6. Reach out to the mods for help with any problems or disagreements. We want the Sticker Exchange to be a safe place for everyone.

Additionally, please remember that selling posts are not allowed on this subreddit.
