O2 have released an absolutely brilliant app which enables you to find the best deals in your local area. It is only available to O2 customers, me being one of them.
When you start up the app it asks you for your mobile number and that's it. You can start looking for the best deals nearest to you. You can organise which deals come first, whether they be food or entertainment.
It's very straight forward and simple and I know I will definitely be using it when looking for the best deals in my area.
It's a must have for any O2 customer.
