Peter,
I sent a kit with Priority Mail from Monee, IL , 43 miles from the center of Chicago, to Milford, CT. I mailed the kit on the 21st of April. Two missing sheets of laser cut parts , that were ordered the day the kit shipped, were mailed from Southern California to Milford and arrived on the 24th. The kit arrived on the 27th. The tracking on the kit was really strange it went to Connecticut, them Massachusetts, then back Milford, Connecticut. The package I talked about above went from Reno, to San Francisco, to LA, to Memphis, TN , then Chicago and finally to Monee. The USPS edits tracking when a package has been delivered to cover up the ridiculous routings, the final tracking did not show the Memphis stop that was in an earlier tracking. I agree that the USPS is normally does a good job, but right now I am seeing package routings that appear to indicate packages are being put on any transportation going in the general direction of the final destination.
