FAQs

Does Whistles have free delivery?

Yes, you can get free delivery on purchases of £150+. If your order is less, standard delivery will cost £3.95. Your order should arrive within 3-5 working days. If you need your purchase before this, next-day and nominated day delivery costs £5.95.

Do Whistles do Blue Light discounts?

Do Whistles do student discounts?

Yes, they do. Whistles now offers 15% off online with a UNiDAYS or Student Beans account for new shoppers. If you’re an existing student shopper, you can still get 10% off with Student Beans.

Are there free returns at Whistles?

Yes, Whistles has free returns within 28 days of purchase. Your item must be unused, in its original packaging, and in re-sellable condition. You should also keep any ‘do not remove’ tags attached, or you will not get a refund. Sadly, you cannot return face masks or pierced jewellery for hygiene reasons.

Hints and Tips

Newsletter discount: Sign up for the Whistles email newsletter to get 15% off your first online purchase. You’ll also be sent regular sales updates, new product notifications, offers and promotions. Email subscribers usually save more, with these sales updates and discounts.

Refer a friend: Refer your friend to Whistles and they’ll get 15% off their first purchase with your code. Your friend will need to be over 18 and purchase a full-priced product for this discount. Once your friend makes a successful purchase, you’ll also be sent 15% off your next purchase.

Key worker discount: If you’re a key worker, then you’ll get 15% off your Whistles purchase. This discount is for healthcare and NHS staff, teachers, military personnel, charity workers, government staff, care and social workers, and those in the police and fire services. Simply verify your work through the Whistles website.

Shop the sale: Whistles currently has up to 50% off with its sales page. You’ll be able to shop at strong discounts on items from dresses to denim trousers. You can even shop wedding dresses from the sales section. It's worth noting sales change seasonally, so be sure to purchase while items are on offer.

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.
