What is the delivery date on your shipment?
Milsig shipped out a new tank on Monday, the tracking info still has an expected delivery date for Thursday. But as of Friday (today) it still says processed in Richmond. I have called Milsig as this is the second package from them that is late and I have a third shipment that has no date for delivery. Milsig's response was "no one has complained before when we started using Canada Post."
I would suggest if you are unhappy with your shipment you call them as well. I am very happy with their customer service but think they made a poor choice in a shipping company. As the shipee your can't even request a trace on your shipments.
