Who's selling for their old phone for nexus 4

I am pretty excited I am selling my galaxy s3 on Craigslist. Meeting up with a local on Monday at the mall. After reading a few nexus 4 review I was convinced that I needed to make this my next phone. I am just wondering how long it will take to ship and how much tax will be. I am of course picking up the 16gb version. Is anyone else selling and picking up a nexus.

Ps beware of local phone pawn stores. This guy Omar of Omar's Wireless tried to give me 200 for my gs3. He was like that is the most I can give you. I laughed and said I'm getting twice as much for it. These local shops are just looking to make a profit. Buy low sell high.
