At this point I'm pretty sure it's just 2 shipments... One arrived before the other.
That would be something new, sadly.
I always had to fight to get the GCWs delivered to me... that's why I stopped dealing with them (I still like the device, but if I can't get them properly it won't help).
I hope everyone who ordered the GCW does support Fanatic here. He's trying to help everyone getting a GCW, and the delay certainly isn't his fault.
