I like espressos (especially mochas) but they take a bit of work to prepare a single cup. With drip brew, I can do very little and get unhealthy amounts of caffeination into my corpse. Also, I pour ungodly amounts of creamer into my coffee. That Mason jar is quite literally half coffee half creamer.
If cheap, why would they add expense of coffee maker to make instant coffee? Could just boil water for that.
