SAMSUNG S8Plus swap

Description:

I'm preferably looking to swap my S8 plus - black 64gb, unlocked, for an s9plus.

I'm open to any offers, including giving cash ontop for the S9 plus.

No exterior damage to the phone as still a few months new. There is a small black mark to the screen to the bottom right corner approx 0.5cm, refer to the listings images.
