At what point do you declare a package lost?
So I sent a small package to a friend of mine down in L.A. California. I shipped it out last Thursday at my local Canada Post office here in MTL. It was the 3 or 4 business day USA Expedited service I purchased. By Friday afternoon it was accross the border into New York, and from there arrived at a processing center in Bethpage, NY before noon on Saturday. Here we are 4 business days later and there hasn't been any updates on the tracking to tell me if its still there or has left the sorting center. I thought it would have at least been near California by now (but there was bad weather over the weekend and Monday...) So I'm just wondering at what point should I consider calling it in to see if it's missing?
