There are people who have been counting the days until Starbucks annual Frappuccino Happy Hour.

The countdown is now down to hours: The 10-day campaign kicks off at 3 p.m. today.

From 3 to 5 p.m. daily through May 12 — that's Mother's Day, by the way — you can score a frap for half price. And there are so many flavors to choose from (caramel, chocolate cookie crumb, mocha, cinnamon dolce, hazelnut, java chip, vanilla bean cream ... the list goes on) you likely would not get through them all by the end of the week. Unless, of course, you double-dipped, which at half price might take away some of the sticker-shock guilt. 

  Starbucks has a number of Tucson locations including 802 E. University Blvd., 1821 E. Broadway, 1551 W. Saint Mary's Road, 1767 E. Prince Road and 12100 N. Thorneydale Road in Marana.
