Have one locally just a couple of miles from the HF. Some of the stuff is the same- HF's price will ALWAYS be better, usually by a wide margin, on identical items, but they have a lot of stuff HF simply doesn't carry.
I absolutely love both stores and spend large portions of my income in both, too frequently perhaps

They are light years ahead of the Outhouse, excuse me TSC, as far as having stock items actually
in stock.
One really has to watch the prices at NT though, they can gouge you big time. I've made a few impulse purchases there that I returned later after doing a little research and seeing just how much they reamed me. Can't blame
them though for trying, caveat emptor.
Their free shipping to store has mixed results for me- I've had orders literally take 3 weeks to come from their distribution center in Fort Mill, SC, a suburb of Charlotte, NC, to their Columbia SC store...a whopping 75 miles away.
In short- good resource, just be aware of what you are paying. My favorite is their "garage sale" they have occasionally, I've walked out there with literally $600 worth of stuff for $50.
The other thread going about customer service brings to mind a couple of issues with them- recently they ran radio ads for a week here about a 10% off sale on a certain day. On the appointed day I went and bought a bunch of stuff- at the register the clerk said the discount was only for their club members. She was quite distressed as apparently numerous customers before me had given her considerable grief about not getting the discount, which BTW the radio ads never mentioned the club memebership requirement. I demanded to see the manager and got my discount...but jeez..they blew it and should have just sucked it up and granted the discount to anyone that asked without all the grief.
Several years back I paid big bucks for 2nd day shipping on a heavy item that I urgently needed. They charged shipping from their MN location to SC (1000 miles?) but then shipped directly from their warehouse 75 miles away. I would have gotten it overnight anyway for the regular shipping charge, where instead it took 2 days at quadruple cost. I didn't know they had a "local" warehouse at the time. This was before the local store too. Really left a bad taste in my mouth and when I complained heavily I got nowhere.
So as I said- good resource just watch them like a hawk as they can and will take advantage of you.
