Unless you want the orchid grey then your out of luck. Have been on the phone with Samsung for an hour now going around in circles and buttom line is you just cant purchase a replacement for the orchid grey at this time.
I see this is from 2017.
On Friday July 27 about 9:30 a.m. Central I received what I hoped to be my 3rd warranty replacement S Pen. A box containing an envelope with a letter and 3 Visa cards. Meaning the price of a new S Pen. Thing about it. Letter said Note 8 S Pen NO LONGER AVAILABLE. Samsung .. Nevermind. I will never deal with them again. If this brand new priced used phone breaks under warranty I'll go buy an Apple. A small portion of the story is on my profile. Samsung is trash.
