I did. They sent the money, I held it no longer than 30days. They came and got their truck, I helped, all was well.
YOU SET THE TERMS, and set them how you want, in plain English. A deal's a deal, and don't let anything go without cleared funds IN THE BANK, or cash in hand.
Don't be scared, be careful.
I sold my MJ to a guy from like Wisconsin or something. Money was Paypal-ed, and a car hauler showed up at my house a few days later. As easy as could be!
