There are several reasons why your HP coupon code may not be applying correctly to your order. First, ensure you enter the code correctly. You can copy and paste it directly from this page to make sure you're not accidentally missing any letters or numbers.

If you know you have the correct code, but it still isn't working, it may have expired. We test all of the codes listed on this page weekly, which is more than most other sites do. However, coupons sometimes expire between updates. We always list the provided expiration date for each coupon, so you can check if this is the case.

Finally, some HP coupon codes exclude certain items, so there may be an issue with the items in your order. To determine if the items in your order are excluded from a coupon, visit the promotions page of HP's website and click "See Terms" under the code you want to use.
