I got a 42mm Apple Watch Sport (White) off of Craig's List. It was originally listed for 600. I paid 550.00 for the watch. It did come with Apple Care +, so with taxes for my area, I only paid about an extra 50.00 for the watch and got it right away.
50 dollars profit is not a bad price to pay. Given not everyone could be up at 3am.. I managed to sell 5 watches for 200 dollars above MSRP, and that was me not hassling. I got them and flipped them that day.
I don't think these things are worth 200 above MSRP... Unless money isn't really an object.
