I want to buy a second-hand Sony T77 digital camera in Jinan. Who can help me?

It is estimated that the camera is cheaper in Shanda Road Technology Market or Cybertron. Formal invoices should be certified, and ordinary invoices should be issued without watermarks. Come to the store if you have any questions. It is generally not allowed. There are also second-hand ones, but it is not recommended to buy second-hand ones. They are prone to problems and are not insured.
