The longer your packages are on the road the more suspectible they are to damage or loss. I used to use Canada Post/USPS from Mato before he had UPS option. Small packages weren''t a problem, the tank sized ones took weeks, even months and were always somehow misdelivered by USPS at the end. They sat in somebodys customs warehouse for too long.

Then I urged Mato to start using UPS, it was more expensive but I wanted service! My tanks averaged 18 hours through customs now. Always delivered to my door in a timely fashion, FAST!

You get what you pay for, private industry is nearly always more efficient then government.
