(CNN)– Starbucks is hoping to add a little jingle to its slumping sales. Not just the jangling cash register, but also the jungle of holiday spirit. This week, the chain is rolling out its seasonal cups. Starting on Thursday, Nov. 7, customers at U.S. locations will get their hot drinks served in one of four festive cup designs. Starbucks describes them as having “familiar shades of Starbucks green, and cranberry red paired with fondant-inspired soft pastels”. The cups are a Starbucks tradition, one that has boosted revenue in the past, which the chain desperately needs. Categories: News Tags: Starbucks
