Are you saying that the beans that Big Roy, Thunder, etc... offers is a higher quality / better bean than the Jablum, Wallenford, etc.. that are sold in the airport store?
If that's the case I will make a point to look one of them up next trip. I meant to last time but... well you know how that goes.
I always go with a list of things I'd like to do, see, try but never get to all of them.
