Grand Bazar, Istanbul
This shop was selling musical instruments. I picked up a Turkish wind instrument (I'm unsure of the name, but it has a double reed, looks like a recorder and makes an awful noise when I play it). I bargained the dude down from 70 lira to 50 lira (about $25), with four reeds. I suspect he was still making a substantial profit margin. Once I'd bought it, I got him to play another instrument and grabbed a photo.
