I was in Hawaii for two weeks in June on my honeymoon. A week in Maui and another week on the cruise ship visiting all the main islands. I personally thought Kona coffee was a bit overrated. I did pick up some Kauai coffee (blue bag) while I was out there as it was more reasonable priced and they sell it at Wal-Mart. I would hardly call it super expensive. The coconut caramel crunch is very very good!
Dunno if the coffee is really worth trading games for.... and a bag or two is definitely not worth the value of Bonk 3 or Super Star Soldier. They have their one website and ship coffee all over. Not trying to ruin your chances at a trade, but just stating the obvious.
