In what the blogger thought was an inspired move from an economy and convenience standpoint, he bought the immersion heater shown above for $8.55. Hmm, let's see, with coffee going for $1 to $2 at roadside stores, with motels providing inadequate or no coffee and campgrounds never providing the morning brew, it would be just a few cups before the blogger recouped the cost of the heater and started saving big, using wonderful ground coffee he buys in bulk and carries with him. The blogger used the heater four times, then it stopped working.
