While driving around doing errands I like to have something to drink (preferably tea) available.
To avoid paying anywhere from $1.49 to $1.99 per 16 oz. container at a convenience store, I make my own before leaving the house.
I keep a jar of store brand instant tea on hand and make a cup as I need it. That way, I save time and money by not stopping for something to drink while out shopping or running errands. Saving $2.00 or so a glass may not seem like much at one time, but that can easily add up to more impressive amounts, when I figure it out over the course of a week or a month.
