So I've got a fully unlocked Samsung S8 regular size that I'm actually thinking of listing for an even trade for a like new Mate 9. Would this be a fair trade or would I be selling myself short on cash my way? My S8 is less than two weeks old. Would I be better off selling it outright and then buying a Mate 9 instead? Has anyone used both of these phones or have experience with both devices? I am not even sure what type of value my new S8 has compared to a new Mate 9. Can anyone throw out some suggestions or feedback to me in which direction I should take? I know the Mate 9 is going to be larger than my S8 which to me is the biggest difference. I also see where I can get a Mate 9 for $435 from Amazon warehouse with original packaging. Does anyone know what my S8 is worth? It's the Arctic Silver regular size S8 that comes complete with all contents. How much is my S8 worth and or how much should I list it for. Anyways I thought about listing it as a direct trade but the more I think of it the more I think I should possibly just outright sell it. Can anyone help me with the price point of my S8 and then the price point of a used Mate 9? Thanks for any help and also for those who use the Mate 9 daily please give me your thoughts on the new it. Thanks a bunch!
