How do we source promo codes and deals?
We have an experienced team of 5 deal experts based in our offices in Cardiff and London, who are dedicated to finding promo codes, deals and sale highlights for Marie Claire vouchers.
Our London team keep in touch with retailers directly to get a heads up on upcoming discount codes as well as negotiate exclusive promo codes that you won’t find anywhere else. Meanwhile, our Cardiff team partners with affiliate networks and research the web to source the latest discount codes, and put them right here on our dedicated retailer pages. The offers we show you are updated at least twice a week.
To top it off, we have a Bath-based team of editors that have a background in saving money on fashion and beauty products. Using their experience and knowledge of the industry, our editors seek to offer additional ways to save at the retailer outside of using a promo code. Our FAQs and money-saving tips about each retailer are fact-checked and updated every three months.
What if my promo code doesn’t work?
We try hard to avoid listing promo codes that don’t work. To do this we:
- Test the promo codes ourselves to make sure they’re valid.
- We don’t list unique codes that only work once.
- We give as much information as we can to avoid any terms and conditions trickery.
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 vouchers.marieclaire@futurenet.com and letting us know.
How do we make money?
It’s simple, we get a small percentage of the money that you spend with a brand or retailer - a commission. When you use deals and promo codes listed here at Marie Claire vouchers, we get a small share of the retailer's profit as thanks for helping them connect with a new customer. And that’s how we make money while you save money.
