Coffee for gift.

[Midnight Rambler]

Hilo farmers' market is a good place to look for stuff from some of the smaller farms. My parents also like Shark's coffee a lot, both Kona and Hilo-grown (not sure what their actual sources are, presumably they buy from various farmers), and it's less expensive than some of the others. Somewhat surprisingly, Long's in Hilo has quite a selection of local coffees (they also sell the 10% blends and ground coffee though, so be careful in what you pick out).
