Great question! Here is some rough math:
10 days of coffee for 4 people + 11 days of coffee for 2 people = 62 cups of coffee
Most days I also had an afternoon solo coffee, so lets add another 15 cups.
77 cups of pour over coffee at $4 per cup (pour over usually costs this much or more) = $308
Cafflano Klassic - $75
Coffee Beans - $45 ($15 x 3 bags)
$308 - $120 = $188 of savings.
The convenience of fresh, great tasting coffee = priceless.
