Starbucks is bringing back their summer refreshments: Hibiscus Berry and Cool Lime! Except this time, they will be permanently keeping this drink on their list year-round. On July 13, 2012, they will offer free tall samples to all customers who ask for it. Starbucks will only be sampling for three hours: 12pm-3pm! Their reason for sampling is to get their sales higher and more people knowing about their Refreshers to buy them year-round. Happy Refreshing on July 13th!
