This replaces an earlier sticky topic I made recommending Couponshy as a way to always have 20% off coupons, free items, etc. found at
http://seprepnet.com/forum/index.php/topic,2382.0.htmlhttps://couponshy.com/harbor-freight-coupons-promo-codes/ is still good for pulling up the latest 20/25% of coupon and free items. Incidentally, they almost seem to be moving away from free items with only three showing right now.
A little better is the Android app "Coupons for Harbor Freight Tools" on the Play Store at
https://play.google.com/store/apps/details?id=com.g2018.hfcoupons&hl=en_US - this shows all the active Super Coupons in addition to % off coupons and free items.
The BEST, though, is both a website and Android app at
https://www.hfqpdb.com/ - the best thing about this one is that it's SEARCHABLE. If you're looking at paper ads or even the above app, the coupons are presented all willy nilly and visually scanning through them can be overwhelming. With the searchable database, you can type in "generator" or "screwdriver" or whatever, and it pops up the appropriate coupon. I'm finding to stay away from plurals when I search. "Screwdrivers" won't turn up "screwdriver set".
The Android app is particularly nice in that it has a coupon vault. As you're shopping, you can add individual coupons to the vault. then when you get to the register, they're all in one place so you can scan, swipe, scan... it goes really quickly.
The drawback for some people is that the Android app isn't a Google Play Store app and you have to enable permissions for third party apps. But you have to enable any permissions for it to access anything, so not much can really go wrong, if anything.
You can use it on the browser of your computer or phone if you don't want to install the app or if you have an iphone - you just don't get the functionality of the coupon vault.
Happy shopping!
