Go on eBay, look up what the designer/make of the shirt you are selling usually sells for, and put your price a good bit below that (To facilitate bidding). Don't forget to check what shipping is going to cost you so you can put it in the selling information.
EDIT: And when you put it up, check off the option to donate a portion of what you receive from the bid to a charity, unless you are a soulless bastard.
