Anytime I have to go to the Frontera, I try to stop by one of the supermarkets and pick up a bag of 1820 Coffee. It is a Costa Rican coffee that I like better than most Panamanian coffees. The cost for a 1,000 gram bag of beans (approximately 2.2 pounds) was $10.05 on Wednesday.
It is always good to buy coffee by the bean because you know what you are getting. It has been said that many brands in Panama use fillers to improve their profit margins. If you grind your own coffee beans, then you know what you are getting.
