For Android users – go to your ‘Saved Offers’ and click on the offer you no longer want to use, at the bottom of the screen there is an option to ‘Unsave’ the offer.
For IOS users - go to your ‘Saved Offers’ and click on ‘Edit’ at the top right of the screen, select the offer you no longer want to use and click on the bin icon at the bottom of the screen, then click done at the top right
This is silly for Android. On iOS you can select multiple offers and "unsave" them, but on Android you have to go to each saved deal that you want to "unsave".
