*Harbor Freight is no longer issuing 20% coupons like they have in the past. We will update this page whenever a new one comes out however I have a feeling they will only be good for a couple of days at a time.

Some users have told us that Harbor Freight is not taking 20% coupons from their phones. These stores are doing this outside of the Harbor Freight coupon policy. Here is a screenshot from the Harbor Freight homepage, Click Here. Note the screenshot also says that you can print the coupon. If your store is giving you a hard time you can try printing the coupon OR show them a text message. As you may know, Harbor Freight has a text message service that will text you coupon codes. Here is the exact text you receive. Just text this message to yourself.

    The 20% off coupon without the Central Machinery exclusion would not work in store nor online for Central Machinery branded products. Man I would love it if it worked!! — But it did not.

    20% off super coupon does not work online for the central machine tools. I don’t know about the store. Here is a 100 dollar off coupon code that does work for the 2hp milling machine. 39382246

    I’ve been experiencing something weird lately… For the last 3 days I have tried to order various different “Pittsburgh Pro 1/2 drive ratchets” using the famous $5 off coupon that has no expiration date. And it wouldn’t work on any of them! I get an error message online when entering the code. It says something like “Coupon code 50223675 has reached it’s limit”. I have tried almost all of them. And even 1 ratchet by itself. Nothing works. I hope it’s just a temporary computer bug. I am worried that they “killed” the coupon that isn’t supposed to expire. I love Pittsburgh pro ratchets, I was slowly working my way through all of them. I started with 1/4, then 3/8… And was trying to finish my collection with the 1/2’s…

      I just used that coupon maybe 2 days ago on a 1/2″ drive ratchet and it worked. I think the coupon says 1 per customer so maybe if you are logged into your online account it sees you have used it before? That sounds way too sophisticated for Harbor Freight but maybe try using the coupon without being logged in.

    The 30% off an item under $10 is not a valid coupon. Tried it at my local Harbor Frieght. They typed in the numbers and scanned. Not valid.

    The 30% off coupon which is valid thru 4/7/19 from Javier did not work in store or when entered at HF online. They mentioned it was a 3rd party coupon and are waiting to hear from corporate to figure it out.

      Stopped back in to see if the store found out anything about the 30% off coupon. They will accept the coupon but not until April 1-7. They had no further comment.
