Caribou Coffee is brightening afternoons in June. Every Tuesday and Thursday, the coffee chain is offering customers a FREE cold beverage (of equal or lesser value) with the purchase of one at regular price — after 2 p.m. The offer excludes bottled drinks and is limited to one per person. To get the freebie, you must mention the offer — click here. (If you’re looking for something hotter, get a medium brewed coffee for $1.50 all day on Tuesdays and Thursdays in June. Again, you must mention the offer.) For cafés in Colorado, click here.
