PAUL UK have introduced exclusive in-app offers to Go Vegan in January. You can see the announcement in your app.
To take advantage of the in-app offers, go to your “Make a Saving” section which is located under the “Invite a Friend section”. If you cannot see it, simply reset your app - that is to say close it in the background of your phone - and the Make a Saving section will appear.
When purchasing in-app offers, the payment card linked to your app will be charged immediately and you will receive a voucher to use in your voucher carousel.
