How to use a O2 discount code

O2 discount codes provide you with an online saving which is redeemed during the checkout stage on the O2 site. They usually provide a percentage off based on the amount you spend, but can also be for a set amount off.

To claim your discount you just need to click on the Get Code & Open Site button, which will then display the voucher code for O2. Copy this code and then paste it into the code box when prompted on the O2 website. The total amount saved on your order will then be displayed before you complete the transaction.

Please ensure you check the terms and conditions displayed as most discount codes for O2 cannot be used in conjunction with any other offers on site, which means they will not work with sale items.
