Costa is giving away FREE slices of cake of your choice on your birthday when you join their 'Coffee Club'! As a member, you can also enjoy other perks such as a FREE coffee once you have purchased others! What a lovely initiative to reduce waste.
To claim yours simply click 'GET FREEBIE' then 'Join the club' then if you have picked up a card click yes and register it, or press no and download their app to get started. To do this open the "Settings", then tap "View and edit birthday" and enter your date of birth.
What a lovely way to celebrate!
