How the calculator works: an example
Example: you're buying a new Apple iPad at O2 for £699.00, and you have a 10% off code. If a 40% sale is on and the code also works on sale items, the sale takes off £279.60 and the code a further £41.94, so the basket drops to £377.46: a saving of £321.54. Press “Fill in the example” to see it worked out, or put in your own basket, sale and code. Whether a code works on sale items depends on its terms.

O2 shopping FAQs
Is there an O2 promo code or discount code?
Most O2 deals are price cuts and airtime offers that need no code. Codes come from schemes: students get a basket code from UNiDAYS or TOTUM, and existing Pay Monthly customers are sometimes sent a voucher code by email or text, which takes money off the upfront cost of a new phone. Enter it in the "Got a Promo?" section before you check out.

Does O2 have a student discount?
Yes. Students get 20% off the Airtime Plan when they buy a phone, tablet or mobile broadband device on O2 Refresh, and 20% off selected accessories paid for upfront. Get the code from UNiDAYS, UNiDAYS GRADLiFE or TOTUM and add it at the promo code step; it doesn't work on Ultimate Plans or devices that already have free airtime.

Does O2 give an NHS or Blue Light Card discount?
O2 lists exclusive savings for Blue Light Card members, a card NHS staff, teachers, emergency services and armed forces can join. There's no code to type: the member pricing applies when you go to O2 from your Blue Light Card account. The pages we read on o2.co.uk mention no separate NHS discount.

Is there a discount on O2 SIM Only plans?
SIM Only plans take no code. If you already have an O2 plan, Multisave takes 20% off the airtime of each SIM Only plan you add to your account, and students' 20% airtime discount is for plans bought with a device on O2 Refresh.

Does O2 charge for delivery?
No. Standard delivery is free on all devices, SIMs and accessories, and in-stock phones and tablets ordered by midnight Sunday to Thursday arrive the next working day in most of mainland UK. A chosen morning, Saturday or Sunday slot costs £9.99, and click and collect from an O2 store is free.

Can I get money off a second O2 phone or SIM?
Yes, with Multisave: every extra eligible phone, tablet or SIM Only connection you add to your account gets 20% off its Airtime Plan, for up to 20 numbers. The first number isn't discounted, and it can't be combined with other airtime discounts.
Source: o2.co.uk, read 1 Nov
Why won't my O2 promo code work?
Only one voucher code works per order, and emailed voucher codes are for existing Pay Monthly customers buying a phone on a Device Plan, before the expiry date in the message. The student code doesn't work on Ultimate Plans, on devices with a free-airtime promotion or on spread-the-cost accessories.

How long do I have to return an O2 phone?
You can change your mind and return a device within 14 days for a refund. A faulty device or accessory can be returned within 30 days of purchase for a repair, replacement or refund; some accessories, such as earphones, can't be returned for a change of mind once opened.
