If you don’t have a tumbler or travel mug, Starbucks will have them for 20% off for today. In addition, as a standing policy, anytime you bring in your own tumbler or travel mug to a participating Starbucks, you get 10 cents off your drink every day (also true of asking for a "for-here" cup).
Even if you don't have a reusable mug or tumbler and don't want to buy one, you can still get your free brewed coffee or tea by asking for in a "for-here" cup (i.e a mug or glass).
