Promio is an independently run coupon site. Every code published here is tested by hand against a real cart, and each one records the date it was last checked.

Journalists and bloggers are welcome to quote findings from this site with a link back to the page they came from. Store guides and blog posts may not be republished in full without written permission.
Enquiries
For interviews, data requests or corrections, use the contact page. Include your deadline — we would rather answer briefly on time than fully too late.
What we can speak to
How retailer checkouts actually behave, why coupon codes fail, how discount channels rank against each other, and the seasonal sale calendar. We do not comment on any retailer's commercial terms.
