Coffee and tea can be inexpensive if you brew it yourself. Coffee even less so if you roast it. I've been roasting my own coffee for years now, started with a $100 machine which lasted about 4 years/100 lbs, and then I upgraded to a $350 machine. A pound of coffee costs between $4 and $7, and tastes comparable to something that a boutique roaster sells for $15/12oz. The upfront cost is relatively high, but if your enjoyment of coffee is encroaching into the realm of "hobby" then it's absolutely worthwhile.
