Yes, you can purchase beans from Big Roy at Cafe Goa. I haven't tried his coffee recently, but it always gets solid reviews.
Lately, I've been buying a small bag of High Mountain grounds at L&M or Wise Choice, for making coffee in my room. If the bag is fresh, I find the High Mountain grounds to be very good. I then pick up a pound of Blue Mountain beans to take home. We'll see how it goes on my next trip, as far as pricing. If the Blue Mountain beans are out of control, I will probably just buy some High Mountain beans to take home. I've been meaning to try Thunder, as well.
