Frequently Asked Questions O2

❓Is it possible to use more than one discount code?

Of course! Sometimes you can combine specific discount codes with other codes during an event or sale period with an online store, to increase your savings even further. Usually however, only one discount code may be used per transaction with online stores. Sometimes, a store may produce multiple codes that can combine with unique deals and offerings to maximise your benefits during a sale or event throughout seasonal or annual days. Double check the terms and conditions for your discount code and/or the event to make sure you understand whether you can or not!

💡How do I apply a O2 discount code at the checkout?

If you want to save money on your total or part of your order, get free delivery, free gifts or any additional benefits with your order, a discount code is the perfect solution. Choose a O2 discount code from the long list of codes from the O2 page with Mirror. Resume your shopping tab with the O2 page open and go to your basket. When you checkout you should see a discount code or promo code input box that allows you to enter a O2 discount code. Check back over your order and ensure that it meets the correct conditions set out by O2 in their terms and conditions for the discount code to work. When you are happy with your order and the desired promotion or event, copy and paste a code from the O2 page and enter it into the discount code box. The price reduction, free shipping or outlined benefit will be automatically applied to your basket. You can now progress onto purchasing your items with your amazing discount code applied!

🕒When do these promo codes expire for O2?

Each promo code has a unique period of time where it is live and can be used, due to the ongoing promotions and events that are starting and ending throughout the year. This is why it is really important to check back with Mirror Discounts constantly to see the latest promotions and deals on offer for your favourite brands, just like O2. You can take advantage of flash sales during weekend or midweek events, new customer codes or limited time exclusive codes, all of which have varying time limits. You can see the expiration date on the Mirror Discounts O2 page next to each specific code or sale event, so you are kept up to date! Be sure to double check the O2 terms and conditions for the exact expiration date of the code or event, when you use it to purchase your items at a lower price.
