I've given up my iPhone 6S Plus in lieu of a simpler and less expensive phone, as I intend to switch to a tablet for all my media needs, effectively planning to replace my computer itself as my needs have changed in recent years. So since I no longer have the iPhone, I'm now selling my Mophie Juicepack, which has served me really well during its usage:

On the one hand, this case will make your phone noticeably heavier, but IMHO you get used to it after a few days to the point where you don't notice it anymore. But on the other hand, it comes in REAL handy for when you're out a long time, have no time or access to charge the phone, and especially if you're a power user. It says it recharges your phone upwards of 60% of its capacity, but to this day I've been getting around 70%. In other words, with your phone fully charge and the case also fully charged, you can go all day and then some before having to charge either, and that's if you are a heavy user who checks websites often, plays media, etc.

As the pictures do show, it has a couple scuffs on the back from wear and tear, but not once have I actually dropped it. I take very good care of my phones and [i]always[/i] put a temper glass screen protector on it first thing when I get it as well as said case.

This case typically retails at pretty much $100, though the gold colored one I have came down in price a bit: http://www.bestbuy.com/site/mophie-juice-pack-external-battery-case-for-apple-iphone-6-plus-gold/2146113.p?id=1219530054688&skuId=2146113

Rather than quote a price, I'll let anyone interested quote ME what they think would be a fair price for both themselves and for me. I do have an amount in mind, but I'd like to hear what you're willing to pay for it. Consider if the amount is worth it to me for something I paid $100 when making that offer. To be fair, if I accept your offer, it'll include shipping as well. I reserve the right to reject any offer I feel is too small.

That being said, if the amount is indeed fair to both parties, you'll be getting a helluva deal out of this.
