Where can someone buy a great bag of kona coffee as a gift to bring back to the U.S. mainland for a coffee lover. What time of year is best to buy it? Do you recommend a specific company? Price range is $75 or under.

Will be able to fly into Kailua-Kona, Honolulu, Kahului, or Kauai.

I've never been to Hawaii, and have never tried Kona coffee. Forgive me if this question sounds silly.
