I have checked the prices over here in Lahore and based upon that I have asked for what was quite reasonable as per my standards.
If the price is what you have mentioned in Pindi/Islamabad then still am asking a reasonable price as I have hardly used it and also 4/5K is quite a difference as far as a mobile handset is concerned. People here are demanding 38K ~ to 42K for something which is atleast couple of months old.
Anyways am still open for reasonable offers
p.s. By the the site which you have mentioned is not trustable at all. Call them and ask them for delivery and then you will come to know that they are out of stock in most of the cases.
