Woohoo! I just got off the phone (AGAIN!) with Andrea at customer service, and got this clarification on the Status of your order.

"Pending Shipment":
Means unit is out of stock or one isn't allocated to your order.

"Has Products Pending Shipment"
Means unit is in stock and one is allocated to your order. it's just waiting to ship out.

This makes sense as to why we've been seeing order status fluctuate between these two values.

Hope that helps some of you out there. I was told my order should ship soon, "sometime within the next week". I ordered in the evening of Dec. 28th (CST).
