Instead of purchasing ready made ice tea or coffee, make your own.  Brew a pot of tea or coffee, flavor it as you like it, and keep it chilled.  Place at least half of the chilled drink into ice cube trays and freeze it.  When frozen, place the cubes in a freezer bag.  When you pour yourself an iced drink, add your frozen tea or coffee cubes instead of ice cubes, and your drinks will not become diluted.  This works well with lemonade and other juice drinks as well.  Every time you brew your own pot, you’ll save at least $3.  Put the savings in your tin.
