Query: um, it's about the cost

At $10/lb for pretty good coffee from Sumatra or Central America my french press coffee costs me 25 cents per cup and it is FRESH! And the French Press maker I use is now 20 years old, as is the grinder from Krups.So their "Nantucket" blend (and a lot of the others) with this unit is 65 cents a cup. Not counting the maker itself, which has a limited lifespan.I understand that convenience costs money, just want to make sure you do too!
