What if my promo code doesn’t work?
Our team always tries to make sure any out-of-date sales or incorrect deals are not included on our pages. To do this, we check a few things, including:
- Trying the deal and checking if they are valid ourselves.
- Check we don’t have any unique, one-use promotions.
- Looking at the offer conditions to make sure you’ve got all the information.
However, there are occasions when details change or the sales may expire without us knowing. If this happens, be sure to contact us by emailing coupons.marieclaire@futurenet.com so we know.
How do we make money?
It’s completely free for customers to use the deals 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 deal.
