Hi, so I have a cellphone and could really use that leather holster. Can you tell me about it?
Sure, it is a stylish textured leather belt holster that is big enough to hold the following phone types:  iPhone, Samsun g, HTC and many more like those.  It has a felt lined interior and a solid metal clip and magnetic latch.  It is of premium quality soft leather.
Is there anything wrong with it?
No there is nothing wrong with it.  It's been gently used.
It has been used? That changes things a bit. I'll need you to come down to $10.
It's almost brand new, It's only been used a few times as I decided to just carry my phone in my purse.  I can let you have it for $15.  That's 50% off the asking price and I feel that I am meeting you half-way in the pricing.  What do you think?
No, you can meet me halfway at $12 and we have a deal. You'll also have to drop it off, as I live 10 miles away and don't want to drive.
Twelve dollars is not actually half-way that's only two dollars more than your $10 price.  I will be willing to go as far as $13, I can understand about dropping it off if you didn't drive but not wanting to drive is a different story.  I cannot drop it off because I do not drive.  But I would be willing to ship it to you for the $13.
