What two things generally define a garage sale aficionado? They like to save money (rather than buy over-priced cups of java at coffee shops) and they like to get to the sale locations as early as possible (before the goods get picked over). A coffee thermos is the perfect solution. It holds enough coffee to keep them alert for treasure-finding and it stays warm throughout the morning. Throw in some quality coffee beans to really get them off to a good start.
