Starbucks Tests Out Reusable Cup Program at Five Seattle Locations | Eater Seattle

"At the kiosk located at 4706 California Avenue SW in West Seattle, customers can request a reusable cup via the Starbucks app with a $1 refundable deposit, then scan and leave the cup at the store kiosk when finished to receive a $1 credit and 10 bonus stars. The experiment launched in March and runs until May 31; returned cups are cleaned by GO Box within 48 hours and reissued, or customers can instead place cups in a Ridwell at-home bin for pickup. Starbucks estimates each borrowed cup will replace up to 30 disposable cups and notes employees do not need to handle returned cups." - Gabe Guarente
