How We Source Our Codes 

At Marie Claire, we have a dedicated team of deal experts, commercial colleagues, and editors who find and negotiate the best promo codes and coupons, as well as produce content aiming to help you shop affordably. 

We have a dedicated team of 3 deal experts that are constantly sourcing and testing coupons and promo codes for some of the biggest retailers in fashion, beauty, and beyond to list on our website. They also work with affiliate networks to get a heads-up on future deals and discounts. This means we can update our pages

Meanwhile, our commercial colleagues are key to keeping good relationships with retailers. Their experience with lifestyle vouchers helps them to negotiate the best promo codes and exclusives for you. 

On the pages themselves, you’ll find carefully researched saving information for all your beauty, lifestyle, and fashion purchases. Our contributing editors have years of experience in the industry and consistently update the page to reflect new ways to save. You’ll find helpful discount FAQs and saving tips which are checked and verified regularly. 


What if my promo code doesn’t work? 

Our team always tries to make sure any out-of-date sales or incorrect codes are not included on our coupon pages. To do this, we check a few things, including:

  • Trying the code and checking if they are valid ourselves.  
  • Check we don’t have any unique, one-use codes. 
  • Looking at the offer conditions to make sure you’ve got all the information. 

However, there are occasions when details change or the codes may expire without us knowing. If this happens, be sure to contact us by emailing info@myvouchercodes.co.uk so we know. You can also go to our contact page.  


How do we make money? 

It’s completely free for customers to use the coupon codes we have above. We’ll get a small percentage of the money spent as a commission from the retailer you shop at. As with most businesses, we do need to make money however this will never impact the price you pay. The brand will give us a small share of the profit for connecting you to them. This helps us keep going whilst saving you more money.

Simply put, the retailer makes a sale, we get a commission, and you get a discount.
