I have put 4 orders through in the past week.
So far so good.
They drop ship, provide tracking number, and have an order summary page where I can track the progress of my order up to the point of being shipped. If the item has been shipped, the tracking number will show in line and provides a link for the tracking information.
I am still trying them, so far I have no problems.
They at least give you a 30 day free trial which I am in the middle of.
As for their shipping rates, they do almost everything through FedEx. I have checked rates on FedEx's website and the shipping rates seem to be reasonable.
