Starbucks frappuccinos 50% off

Starbucks is introducing three frappuccino variations with a huge discount. From 3-5 p.m. May 7-16 Starbucks is having a "happy hour" with frappuccino drinks 50% off. I've never had a frappuccino but I'm excited about this deal.

The three new variations are soy strawberry and creme, extra coffee caramel, and mocha light. It's unclear if regular frappuccinos are also included in the deal. You can sign up for text message reminders if you fear you will forget and RSVP on Facebook. One per customer.

Caveats: at participating U.S. and Canada locations only. Unclear if Starbucks within airports and grocery stores are included. Cannot be combined with other deals or discounts.
