If you’re looking to cool down with family and friends this holiday weekend, stop by Starbucks for these hot deals, both good through Monday, May 30. #1 – After 2 p.m., Starbucks is offering a buy-three-get-one FREE promo — Buy “any three iced or blended handcrafted beverages, and get a fourth of equal or lesser value on the house.” The offer is open to all customers — not just Starbucks Rewards members. #2 – King Soopers is offering any Grande Frappuccino for $3 at its in-store Starbucks cafés. We saw signs for this promo at a few locations. However, we’re unsure, if it’s available at all locations (with an in-store Starbucks café) — so please check first. (Given it’s a holiday weekend, we opted not to bother our usual contacts.)
