I'm recycling 6+ for $175. Therefore, the new price would be
SE: 174 or 274
6s: 274 or 374
6s+: 374 or 474
7: 374 or 474
7+: 494 or 594
8: 494 or 594
8+: 624 or 724
X: 824 or 924
Out of these the best deal seems to be SE for $174, when trying to save money. But my backup is probably about 30GB and it wouldn't fit, which means I would have to buy the $274 one, which seems like a ripoff when you are returning a phone that used to cost something like $800 for a meager $175 and paying additional $275 to get a smaller phone...
There is also the option of paying for a repair from a third party for $150.
Seems like that would be the best option...
