Sure can’t beat free shipping!
One of the prices that one pays for living in paradise is having it stuck to you in so many different ways. Paying the extra cost from the closest costal location would be fair but we have to pay for full cost from distributers /manufacturers location.
USPS Priority Mail is the cheapest and safest way to ship to Hawaii and is usually the fastest – I normally receive an item within two to three days from went it is initially shipped (held overnight on Oahu).
As it takes an additional two to three day for mail sent from Hawaii, to get to mainland destinations . I usually return items for repair through UPS (not ground) as they have convenient location on island and are very helpful. I make sure that the box has to be signed for when it is delivered as I have had problem(s) with theft of items left on doorstep.
If at all possible, I avoid using Fed Express, which many companies require you to use. Since they do not fly out on Saturday and Sunday overnight delivery is a joke, since if you send by USPS priority it will usually get there before. It’s an expensive joke at that - even though they cannot deliver they charge you the full amount, that is unless you can drop everything and bust your tush to deliver it to them at the airport early Friday morning before the one flight leaves.
