For all you know, the
Seriously. And I'd rather have my phone sitting around at a secured hub than at my local CC center which has been known to lose and or not deliver packages. I once got a notice that something had been delivered, and it wasn't at my house when I got home, so I thought it was stolen. A week later, I had to pick up another package that I'd missed, and lo and behold, they brought me out two packages. The one that had been "delivered" a week prior was sitting in their back room the whole time. I'd already contacted the vendor and asked them to re-send it.
tl;dr - it's safer to have them all sitting in a central facility that works on massive-volume logistics than my local CC where stuff routinely goes sideways.
