Sip on savings at Peet’s Coffee & Tea. The Berkley, California-based coffee chain is giving customers a summertime deal — buy any handcrafted beverage and get a second one for FREE (of equal or lesser value), every Friday from 1 p.m. to 3 p.m., through August 25. No coupon required. (See promo tweet for details.) Die-hard fans, or “Peetniks” (as they’re better known), claim it’s the best coffee shop anywhere. However, unlike its ubiquitous “green-strawed” competitor, Peet’s Coffee & Tea has only 3 cafés in Colorado – Boulder, Centennial and Denver.
