From today until May 14, participating Starbucks locations take 50% off any Frappuccino blended beverage when you visit between 3 pm and 5 pm local time for Frappuccino Happy Hour. Even better, My Starbucks Rewards members who pay with a registered Starbucks card can get this deal from 3 pm to 6 pm local time. (Not a member? it's free to join). That's tied with our December mention as the best deal we've seen on these Frappuccino beverages at Starbucks in the past year. Click here to find your nearest location.
