How We Verify and Rate Our O2 Discount Codes

We understand how frustrating it is when discount codes do not work as promised. We are shoppers ourselves, so we do everything we can to ensure that we always share the latest active discount codes.

Our community of buyers - Every time you use a discount code fromUCVoucher, we ask you whether the code worked or not. This feedback helps us share the best active discount codes and assist other shoppers in saving more money faster. We find and publish discount codes FAST - We discover tens of thousands of new discount codes daily and publish them as quickly as possible. We know that some discounts and sales can expire within hours, so we always publish them as quickly as we can. We do not steal discount codes - Many discount code websites simply steal codes from other sites - this happens to us constantly. We know how important it is to share only current, working, active codes, so we find and share only codes from official sources, including a store's website and their marketing materials.

How to Apply Your O2 Discount Code

Here's how to apply a O2 discount code:

  • Find the O2 discount code you want to apply on this page and click the "Copy Code" button. The code will be copied to your phone or computer's clipboard and is ready to be pasted at checkout.
  • When you're ready to check out on the O2 website, click "Go to Checkout" or "View Cart" to start the checkout process. When you get to the payment step, look for the "Discount Code" field and paste the code in.
  • Click "Apply" to add the discount to your order.

Why You Might Not Always Find a Working Discount Code

There are many reasons why a discount code might not work, but these are the most common:

  • The code has expired - Every O2 discount code eventually has an expiration date. We know it's frustrating when you can't get a working code, so we do our best to keep our discount codes up to date.
  • The product is already on sale - Some stores offer sales and discounts without the use of discount codes. If you want to know if a store is currently offering sales or discounts, you can usually find this information on their website or on their social media accounts.
  • The code is not valid for the items in your cart - Sometimes a store has multiple different discount codes available, and only one of them can be applied to your purchase.
  • There are other restrictions - Discount codes sometimes have restrictions, such as being valid only for certain products or only valid if you spend a certain amount.

How You Can Still Save Money at O2, Even Without a Working Code

Even if you can't find a working O2 discount code, there are still many ways to save money quickly at most online stores. Here are some of our best saving tips:

Free Shipping and Returns Lead to Big Savings

The cost of shipping your purchase can make up a significant portion of the total amount you spend in a store. If you change your mind or buy the wrong size and add the costs for return shipments, you could lose money on products you ultimately don't even keep.

Understanding a store's shipping and return policies can help you save money while shopping smarter. Take advantage of offers for free shipping and returns to order multiple sizes and find the perfect fit, or to try items you normally wouldn't buy, with the assurance that you won't have to pay for shipping or return costs.

Save Later with Cashback Rewards

While some stores may not offer direct discounts, you can still save money by using cashback offers for your purchase. Make sure you've explored all the cashback options in a store before buying - even if you've already found a working discount code.

Look for an Email or Sign-Up Bonus

Most stores offer you a discount or bonus just for signing up for their email newsletter. This is usually a percentage off your first order or a fixed amount off your purchase.

Leave Your Cart Behind

If you place items in your cart and leave the website without completing your purchase, many stores will send you a reminder email with a link back to your cart. This email often contains a discount code to encourage you to return and complete your purchase. It might not work with every purchase, but if you have time, it's definitely worth a try.

Check for a Referral Program

Referral programs are a great way to save money, as you can be rewarded for referring friends and family to a store. Many stores give you a discount code or discount just for referring, and some even give a bonus if the person you referred makes a purchase.
