USPS 1st class mail and USPS parcel post has combined and it its called Ground Advantage. More information here >>> Ground Advantage | USPS
Since the Maui (Lahaina) fires all mail going to Maui has been rerouted to Honolulu where I am located. There have been recent shipping issues that I am slowing finding out the cause. 1st if the mail from Maui causing delays and packages being sent by ocean freight (ship). 2nd the mail now doesn't get sorted by workers because they are overloaded with packages. The way it works is it separate smaller packages from larger packages so some smaller packages get accidentally gone into the ocean freight bin. 2nd issues is if you are shipping any flashlight with a battery there is a small chance it will go ocean freight, so I ADVISE YOU TO USE FEDEX 2-DAY!
ALL PACKAGES UNDER A 1LB SHOULD BE GOING AIR FREIGHT! PRIORITY MAIL WILL AUTOMATICALLY SHIP AIR BUT UNDER CERTAIN RESTRICTIONS. IF THERE IS BATTERIES WITH YOUR ORDER ITS POSSIBLE IT WILL BE PULLED AND SHIPPING OCEAN FREIGHT, I HAD SOME PACKAGES THAT HAS GONE THIS WAY! IT'S HARD TO SAY I THINK THINGS WILL CLEAR UP AND WILL GET BACK TO NORMAL SOON.
