Discounts are awesome. Discounts at places you go to on the daily like Starbucks are even better. Therefore, getting a discount on Starbucks Frappuccinos is better than awesome.
If you're a member of the Starbucks Rewards program you can get any Frap for 50% off on Monday, March 7, 2016. The deal runs from 2pm - closing at participating locations and you'll need to pay with the Starbucks app or a registered card.
There are actually a bunch of deals going on Mondays in March for Rewards members, which you can check out here.
Hopefully the weather warms up enough to warrant an iced beverage come Monday. But then again, you could just drink your Frap with the heat on blast. Just don't tell your roommates why the gas bill is so high.
