Bring a cup:
Customers get 25p off all drinks if they bring in their own cup/tumbler. Starbucks have also started charging an extra 5p to those who takeaway drinks in its paper cups.
Grab a Starbucks reusable cup for £1 which you can also take to other outlets.
Save the ice and your wallet:
Iced drinks can be significantly watered down when ice is added - up to 50%!
So we have a sneaky tip - ask for light ice or ice on the side. You can get more of your actual drink rather than paying for a cup of ice.
