Get as much as $300 for your old phone
While the entire process is rather simple, there is a drawback. The money you get for your old handset from Samsung is not as much as you would get arranging a private transaction, but it is a lot easier. Even if you purchased your new Samsung smartphone 30 days ago, along as you have the proof of purchase, you can still take advantage of the deal.
