TL;DR Samsung briefly listed the $2,899 Galaxy Z TriFold on its US store page earlier today, but there was no trade-in option. At $2,899 plus tax, the Galaxy Z TriFold is already asking a lot. As 9to5Google spotted, Samsung briefly put the Galaxy Z TriFold up for sale on its US website earlier today, ahead of its official launch tomorrow. While buyers could see pricing, bundles, and add-ons, the usual trade-in option was conspicuously absent. The lack of trade-ins for the TriFold today also contrasts with the explicit mention of them that a Redditor spotted on Samsung’s site earlier this week.
