About Us

What GraphEffect is

GraphEffect is a coupon and deals directory. We collect discount codes and offers for online merchants, test them at checkout, and publish what we find — including when a code does not work.

Why we started

Coupon sites are full of codes that expired years ago, dressed up with today’s date. Trying eight dead codes to find a live one wastes more time than the discount is worth. We built this to be the version of that we actually wanted to use: fewer codes, checked properly, with the date of the check on the page.

How we work

Read how we verify coupons for the testing process, our editorial policy for how pages are written and reviewed, and our affiliate disclosure for how the site is paid for.

Contact

See our contact page. We read everything sent to us, and reader corrections are the main reason expired codes come down quickly.
