If you have received unnecessary badges, the first step is to ensure that these badges are inactivated on your account, if you haven't done so already.
If you find yourself with badges that are no longer needed, you have two options to consider:
Option 1: Keep the badges for the duration of their wear period. Should you require a badge during this time, you can easily reassign the unused badge to another wearer. If the badge goes unused for the full wear period, it should be returned with the others at the end of the wear period.
Option 2: Return the badges along with the current set that you are sending back.
* Please note that badges are charged for at the time they are shipped.
