I posted my unlocked 5s on Craigslist and many interested people have responded to the ad. Honestly, I am a little leery of meeting up with people & making cash deals. I have proposed meeting at the Apple Store. I'm not really worried about getting robbed, but more so of someone dropping counterfeit cash on me of even coming back later saying I sold them a bad device (phone is in pristine condition). This my first iPhone sale and I was wondering if anyone can offer me any tips or things to look out for when doing this to help ensure a smooth process.
