I have a few things for sale but not many sale. A lot of the older avionics are hard to sale with everyone upgrading.
Local buyers always meet in person at a public place. There are some police stations that have designated areas in front of their building for people to meet. Payments are PayPal goods not friends and family.That way the buyer is protected under PayPals policy. I never do Venmo. I got burned once on that. There is no protection what so ever with Venmo.
