You can order take away coffee's (and soon, breakfast and lunch take-away's) using the free 356 cups app. Simply download the free app for your iOS or Android device, go to the green zebra online store, and start ordering.
The idea is simple - order using the app, indicating when you'd like to pick up the order. Arrive, pay and collect. (Or faster still if you purchase store credit through the app, pay for it when you first pick up, then each order thereafter will be from your pre-purchased credit)
