During Happy Hour, you can get any Frappuccino for half price any way you like it. Options include various milk or soy, varying coffee intensity, syrups (including sugar-free), and toppings (just whipped cream really).
With temperatures ratcheting up as we edge towards summer, Starbucks seems to have timed this promotion pretty well.
