Hints and Tips

Shop the sales: High street fashion has recently stepped up its game with more expensive-looking pieces—when these are on sale, even better. You can shop from 40-50% off with the Oasis clothing sales on its dedicated ‘Sale’ page. Think relaxed knits, denim basics, and staple t-shirts all at a great discount.

Newsletter discounts: Keep updated on the latest Oasis pieces and enjoy an occasional welcome discount of 15% off. Simply sign up for the Oasis newsletter with your email address. You’ll also be sent the latest sales updates and new arrivals as they happen.

Unlimited delivery: When you sign up for the Unlimited Delivery Pass, you’ll get free delivery all year for a one-time fee of £14. If you’re a regular shopper at Oasis, it’s worth considering. This includes both standard and next-day delivery. You’ll also be sent exclusive offers and be able to access VIP days, with VIP-only promotions.

The Oasis app: Download the Oasis app for exclusive promotions and offers. If you didn’t already know, Oasis has a useful app where you can shop the latest trends from your phone. It’s completely free to download and has 4.8 out of 5 stars on Apple’s app store.

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:

  1. Test the promo codes ourselves to make sure they’re valid.
  2. We don’t list unique codes that only work once.
  3. 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 [email protected] 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.
