From 3 pm to 5 pm local time daily, participating Starbucks locations take 50% off any Frappuccino Blended Beverage. That's the best discount we've seen on these drinks from Starbucks in over a year. (For further comparison, we saw a BOGO free Frappuccino offer for My Starbucks Reward members last week.) Click here to find a location near you. Deal ends May 12.
