I am not an expert on this, but I think that the infrastructure has been set up in order to facilitate speedy delivery. Is there supporting infrastructure that can actually do slower delivery, or do you have to put the lower-priced packages into that speedy service and just hold them somewhere? How do you do that on the back end? I think that's the question. How do you match the revenue that you are deriving from the economy service with the cost to deliver?
I think those are the concerns that Canada Post would have, but I would say—to your point—that the tracking piece has been figured out. I would think that these obstacles are not insurmountable.
