I don't currently live in Hawaii, but I was born and raised there, and my family still lives there.
As Quifish says, Amazon should ship to Hawaii. The other merchants who sell through Amazon may not.
IME, the quickest way to find things shipped by Amazon is to check the "Prime" box on the left menu of the search page. That way, you'll only see items shipped by Amazon.
You can do this even if you don't have a Prime membership.
