You should contact ohio. Or ask if your local chapter sends reps back on a regular basis.
I usually save them up for the year and mail all reps back to the appropriate chapter at the end of the year.
I do not give goblin stamps, or 'merchant' other chapters reps for multiple reasons. But I do send them back, most of the reps i have to send back are from being stolen in game by NPCs, or lost to deaths, etc.
