My listing specifies 3 day handling period; he demanded I ship it the next day (really same day because he ordered it at 11 PM and instructed me to ship it "tomorrow"). He also told me not to include a receipt, and the shipping address is to someone else entirely, so he is probably trying to dropship from me to someone who thinks they're buying from him. He has ONLY left negative feedback for sellers (18 in total and 7 in the last month alone). I don't know that there's enough info to judge that he's a scammer, but something's off/shady, and at a minimum he's unreasonable and demanding.
