As I suspected, giving parcel post a fancy news name of “ground advantage” does not change the fact that to Alaska and Hawaii could take up to 6 weeks as it travels by boat. I purchased an item that is now at 4 weeks and no sign of it beyond San Francisco (I am in Hawaii). As a seller I am not offering any ground advantage and now will be sending out only flat rate priority boxes, which irks me because the smallest still costs $ 10.20. I am tacking on an additional $5 to the item and charging customer $5 shipping so I am not out any money on a sale. Just something to be aware of for your Hawaii and Alaska customers.
