The iPhone 6s Plus, being a legacy model, usually goes for a pretty affordable price on the second-hand market. As of now, you might find one ranging anywhere from $80 to $200, mainly depending on the condition and storage capacity. Models with more storage or in better condition generally fetch higher prices.
When looking for reliable used options, consider checking platforms like Swappa or Gazelle—they offer some degree of buyer protection and you can often see user reviews for extra peace of mind. eBay is also an option, but ensure you pay attention to seller ratings and return policies.
When inspecting second-hand devices, make sure to check for any lingering issues like battery health or screen functionality. A phone’s battery might have degraded quite a bit over the years, so factor in potential costs for a replacement. Nostalgic as it may be, balancing cost and usability is key!
