I generally agree with the positives about the post office. HOWEVER, I had trouble sending a CD in video case with standard DVD packaging from US to Canada. I think I made a mistake in declaring exactly what was in it (Trainz Railroad Simulator). The package never made it. Instead I received the remains of the original shipping label and a little piece of the cardboard box. The post doesn't automatically insure anything or provide tracking. Both are EXTRA. That brings the price right up to UPS ground, which automatically insures for $100 and provides tracking. The PO did give me free postage on my remailing, but they never explained how my package could have been so totally destroyed. I have a hunch someone stole the contents, but we'll never know. Still, I use PO for a lot of small package mailing. If I were sending a uke I would buy the insurance and tracking.
