If you wish to have a feedback:
I believe the opening price tag is too high.
About a year ago Xperia V was sold officially by Sony in shops around this price (350, 380 with accessories and shipping).
Here, even if mint conditions, we still speak about a second hand phone (not the same consumer engagement than a new phone from a shop).
I understand that you wrote price is negociable, but still if you wish to sell on this forum i would advise you to put an opening price more like about half price of what it costed when you bought it new…
