I checked out most safes online. Most companies, won't ship to Hawaii or have in store pick up (walmart, Amazon, Kmart, Lowes, Home Depot, Sams.)
But Lowes does let you order in store and they will ship it to the store here. Problem is that it takes months because it comes by ship with their other stuff from the mainland. So it all depends when the ship will leave port. And you have to pay for it up front. If you want a refund then you have to wait for the safe to arrive then receive full refund.
X-ring sells safes, but they charge for delivery and by step ($10 a step). So you might spend just as much on a safe for delivery.
Fisher sells some security cabinets.
Luckily I ordered from Bass Pro Shops. 1 day shipping was just as much as the safe itself. The next morning I just happened to double check and shipping was $30. So I ordered from there and it came in about a week.
