Kirkland (Costco) 100% Columbian at home. $9.99 for 3 pounds, can't find a better deal. Supposedly it's spensivebuks (Starbucks).
If it's free what JP said, hate to admit it but at $1.07 for a refill 7-11 aint bad.
If sense were so common everyone would have it !

If you want to get really fancy?, try "Kopi Luwak" or "Civet Coffee". It comes from coffee beans that have been eaten and pooped out by a civet. I heard you can order it cleaned, or uncleaned for a cheaper price. But it is very expensive.
