How do I use the 25% off offer?

The 25% off offer is a non-depleting offer, which means that when you have used all of your 2-for-1 offers on one merchant, the 25% off will be applied to your bill instead. Even if you have 2-for-1 offers left, but you discover that the 25% off would give you better savings, you can change this in the order process.
