Have you ever purchased used electronic games from Garage sale ?

I have bought and sold some items during Garage sales and because I test anything I buy before I have bought them I have not had any issues with them. If a seller will not allow anyone to test them before they purchase them, I would advise not to by them. Something like a Wii and or any type of electronic device, the seller should have it hooked up to a TV during the sale for the customers to test, at least this is what I would do so that I did not have issues later.
