O2 Priority is the mobile network's rewards scheme, and members can enjoy a wide range of perks such as high-street discounts, mutilbuy offers and exclusive access to live music events, both on the day and in pre-sales. Join us as we breakdown the best of what the scheme can offer.

Membership of Priority is exclusively for O2 members. You can access Priority by logging in to your O2 account online, or by downloading the app for free on Apple & Android devices and logging in there. Rewards are broken down into tickets and offers. Under tickets, members will be able to see upcoming sales for live events ranging from music to theatre to comedy, which will start up to 48 hours before general sale.

Under offers, you'll see all the discounts and freebies for members. You can redeem the likes of free food and hot drinks every week at Greggs, free drinks at participating pubs & cocktail bars with Thirsty Thursdays, and free cinema tickets every week. You'll also be able to enter competitions for prizes like a £2500 holiday with Jet2, a Majorca Holiday for Love Island finale, and a Disneyland Paris VIP Avengers Campus Experience.

Some of the offers will also grant you discounts on qualifying purchases or initial free periods on subscriptions. For example, members have previously been able to get £75 off Jet2 Holidays, £40 off spa days, £2 off the price of a Disney+ subscription every month, and the first 3 months of a Duolingo Plus subscription for free. Members will also get perks at O2 venues, such as access to priority queues and free use of cloakrooms at O2 Academy venues, as well as discounted drinks and access to exclusive areas in the O2 Arena in London.

As O2 is completely free for all customers and can be accessed just by logging in to your account, getting your hands on these exclusive offers is incredibly easy. You also get a wide range of perks, from free food & drink, cinema tickets and app subscriptions, to discounted events, perks at big venues, and the chance to win massive prizes. If you needed an extra incentive to consider an O2 Tariff, the freebies and discounts on a wide range of categories makes it an appealing choice for money savers everywhere.

O2 have a range of plans to suit everyone's usage, whether you want a huge data limit, to avoid being tied into a contract, a deal that lets you get your hands on the newest phones before your deal wraps up, or just to own your phone outright.

Head to the O2 Shop to see the latest deals and offers. You'll see a selection of contracts, SIM Only plans, phones for sale, and pay as you go options. It's worth checking out the O2 recommendation engine lower down the page, which asks you a few details about your device, usage and what you're after to find the best deal for you. You can choose from a range of payment plans, data allowances, and buy a range of models with variable upfront cost.

O2 regularly offer deals for certain purchases, such as a £300 gift card to spend when you purchase the latest devices, or monthly contracts for tablets and Xbox consoles for low monthly prices. You can search for specific plans or products such as Pay As You Go & Pay Monthly SIMs or phone top-ups by hovering over the 'Shop' section of the navigation menu.

O2 offer free data roaming of up to 25GB in the EU on all their SIMs, and are the only major network supplying the UK to do so, so bear this in mind when choosing your plan. You can also get bonuses by signing up to O2 Perks, including variable data limits month to month, extras like TV & Streaming subscriptions for less, and other exclusive offers, including cheaper upgrades before your contract has finished.

At MyVoucherCodes, we’re lucky to have a team of hard-working individuals who are dedicated to finding you the best possible discount codes, deals and offers that are currently available. We also work closely with retailers to secure exclusive promotions; providing you with unique savings that you won’t find anywhere else.

We keep in touch with retailers and brands

Based in London, our Commercial team is a key part of everything we do. They know the industry, and they work tirelessly to build relationships with big-name retailers in order to secure exclusive offers and rewards that are then passed on to our customers. They keep their ear to the ground for any upcoming offers and sale events too, meaning we’re always ahead of the game when it comes to updating our website.

Our team scours the web for discounts

They work in tandem with our Deal Experts, who can be found at our Cardiff office. These deal-finding wizards scour the web for all of the best discounts and promotions around, before loading them onto our website for customers to enjoy. They also work closely with affiliate networks that keep us informed of the latest offers for the retailers they represent. Our dedicated retailer pages are updated at least twice a week, meaning you can be confident that the voucher codes you’re seeing are up-to-date and valid.

We share our money-saving knowledge

On our retailer pages, you’ll notice in-depth information about the brand and researched hints and tips on how to save money when shopping online. This is where our Category Editors come in - they know a thing or two when it comes to savvy shopping. From technology, health & beauty and fashion to food & drink, home & garden and travel, they keep all pages up to date with content that is designed to make your shopping experience that little bit easier and to help you save money in the process. For more information on the MyVoucherCodes team and the company as a whole, be sure to check out our About Us page.

As a collaborative team, we do our best to ensure that incorrect or outdated discount codes and offers aren’t listed on any of our retailer pages. To do this, we test the codes ourselves to make sure that they work and aim to give as much guidance as possible with regard to how they are supposed to be used.

However, sometimes details change or codes expire without us knowing. If you find this to be the case, you can get in touch by emailing info@myvouchercodes.co.uk or by visiting our contact page.

Using our discount codes is totally free, although we understand that this may seem too good to be true. Like all businesses, we need to make money, and we do this via commission-based relationships with brands and retailers - we earn a small percentage from the retailer every time someone uses a code on our website or clicks through to a sale.

We also make money by offering the brands we work with the chance to buy some extra space on our website, in turn giving more exposure to their biggest and best discounts. And that’s it! By using this model, we’re able to do what we do without charging our customers a penny.
