The new happy hour program will include deals and offers on various espresso drinks, iced tea beverages, Frappuccinos, and more, depending on the day. They’ll also be extending them through the year so you’ll have even more opportunities to get in on the wallet-friendly action. The catch is that in order to get the deals, you have to receive an invitation, which requires downloading the Starbucks mobile app. Also, the deals won’t be available on a regular schedule, so you’ll need to keep an eye on your phone to know when and if you get picked on a particular day. If you do get the nod, you can go in to redeem the deal using the app starting at 3pm local time until whenever that participating location closes up for the day.
