Starbucks fans should mark their calendars and get logged into their mobile apps.

Starting Thursday, Dec. 7, you can get half-off drinks at Starbucks every Thursday of this month.

A coupon for a 50% off drink will be available to reward members in the Starbucks app.

Starbucks is calling the promotion “Festive Thurs-Yays,” and customers are allowed one discounted drink from noon to 6 p.m.

Again, this is only on Thursdays through Dec. 28 so make sure you go on your “Starbies” run this month if you want to take advantage of this promotion.
