Why Trust Us?

Nick Drewe

Founder & CEO of Wethrift

Over 5 million shoppers visit Wethrift every month to find coupon codes for over 70,000 online stores. Wethrift has been helping online shoppers save for over six years, and we take your trust seriously. We're dedicated to being transparent and helping shoppers save as our top priority.

Wethrift is built and maintained by our team of coupon reviewers and engineers, combining some of the latest AI technology with our team of experienced shopping experts to discover and publish over 2,000 new discount codes every day.

We know it can be frustrating when promo codes don't work, or worse, coupon sites publish fake-looking “deals” that won't help you save, just to get you to click on affiliate links. We're committed to publishing only real coupon codes, and being crystal clear about when and how we make money when you use our website.

We put a lot of effort into making sure each page is updated with the freshest coupons possible. We test thousands of discount codes every day to check they are working, and use feedback from shoppers like you to help improve every page on our website. If you've noticed something that's not right, you can report a problem to us.

How this page makes money
