Shipping through the USPS

Sometimes i think Hawaii is the worst for shipping!
FedEx & UPS cost way to damn much ! But get here quickly.
USPS , ground , economy or First class takes 3 weeks at least . But i have had it take 3 months to get here !
Now on other hand , Priority can get here in 3 to 5 working days. To me its worth the extra money not to have to wait so long to receive my items.
Now, Damage is another issue . Most airports here have no cover for arrivals, So if raining your packages get soaked. Also they are very rough with them so things get broken. Maybe @ 60% of my Ins. claims have been paid. Lost out on the rest .
