If you click here and let them know just how wonderful a Starbucks Frappuccino makes you feel they will let you print a $1.00/1 coupon. The coupon expires 6/1/2010.
These typically go on sale at Walgreens 4 for $5 (or $1.25 each). So after coupon you can get a bottle for just $.25. A great deal on a pick-me-up for the afternoon perhaps?
