As marcsand2 suggested, list them here first to give your fellow TESTies first choice. I wouldn't personally buy from the grey market for fear of a scam, but I've happy bought several things from within our org. Next it'll help to take screenshots of the items in your buyback list or hangar page so people know you have what you're listing and can see if it's upgraded, etc. Make sure you've followed the procedure to get your user flair to identify you as the account owner. Finally, look at some of the other sales to get a feel for what people expect. Good luck with your sale :slight_smile:
