12 Apr 2021 --- Starbucks is running a two-month reusable beverage cup trial at five stores in Seattle, US, called Borrow a Cup. Customers can pay a US$1 deposit to borrow a refillable beverage cup, with each one estimated to replace up to 30 disposable cups. Customers can return the refillable cup at a participating store’s contactless kiosk or at-home through a Seattle-area delivery service called Ridwell.
