If you’re looking to save a few bucks, buying a refurbished iPhone 6s might be your best bet and Amazon is offering them for as low as $414.
At $414.99 you can get yourself a 16GB Rose Gold iPhone 6s, which comes with many of the goodies of the iPhone 7, including Force Touch, a better Touch ID sensor, and 2GB of RAM. For just $50 more ($464.99) you can jump up to a 64GB model in Spacey Grey and for $110 more ($524.99) you can jump up to a 128GB model in Space Grey.
You also get to keep the 3.5mm headphone jack if that’s something that you find important. Plus, with an iPhone design refresh expected in 2017, perhaps it’s not a bad idea to spend a little less on something that you can easily sell when the “iPhone 8” arrives.
