Wow, that seems extremely risky for the buyer? He literally gave you $750 and hoped you would keep your end of the bargain? What information did he get from you to go through with that? I'd love to understand why this buyer seemingly took such a huge risk.
i know i just told him i had a lot of emails and other people were offering it.
he met at my house and seen my license to confirm i live there.
signed a contract stated the item and no refunds
