I'm a couponer at HF, but rarely use coupons at any other brick-and-mortar stores. Shopping online I'm always searching for a promo code or coupon though. When HF started limiting what you could use the 20% and the rare 25% coupons on a few years ago I was a little annoyed, but soon remembered how cheap everything was to begin with and continued to use the coupons for what I could.
I bought the HF 4x8' 12" wheel folding trailer with an email flyer that was $50 or so cheaper than the in store price.
I got the 50' 10ga extension cord on sale plus the 25% New Years Day coupon for less than $50 shipped to my house. I couldn't buy 50' of 10-2 SOOW for that, let alone terminate the ends.
The year before I got the HF bench top X2 Clone Mill shipped to my house for about $450 with it being on sale and adding the New Years 25% off. I could have driven to the store, but ordering online someone else had to load it bring it to my house and unload it.
As far as quality goes...
I've yet to break a Pittsburgh impact socket or extension.
I like having cheap wrenches around from HF & thrift shops, so I don't feel bad about cutting or bending one to fit a specific use.
I've had my share of crap from HF too. I bought a dry wall texture gun, it was okay, I did a less than professional but acceptable knock-down in a bathroom remodel with it. It worked so I thought I'd get the little air-less paint gun too, I managed to paint one wall after constant issues, before I was so frustrated that I literally threw it away.
I've thrown away a few of the free LED lights that won't stay on without holding them just right.
I will not use cut off wheels from them anymore, they're not so much cut off wheels as they are little hand held claymores, instant shrapnel.
I've got a HF metric tap and die set, it's okay for chasing threads, but you'll be lucking to get more than two or three holes tapped in anything tougher than PVC. On the other hand I've got a HF pipe thread tap and die set that's been great and tapped dozens of holes.
I threw away most of the HF "vice-grip" style pliers, I had as well, they'd always twist, especially the needle nosed ones. I went to name brand and solved that problem.
I'm rambling again, it really is a crap shoot. I've paid close attention to the Harbor Freight Good Tools List over on Pirate4x4 for what might actually be useable.
