We had a Tractor Supply open up in our small town a year or two ago and I make it a point to do some shopping there, partially because I try not to spend too much money at Wal-mart, which is pretty much the only other game in town.
I usually buy dog food and kitty litter there because it's the same price as Wal-Mart, and I can get in and out much faster. I do use it, as lots of other folks mentioned, to buy bolts by the pound and other assorted hardware items. They always have a clearance section in the back of the store and I've picked up several tools and odds and ends, even some nice leather rifle slings for $10. I get their sale bills/coupons, and they will have good deals on grease and oils periodically.
Not long after they opened, I had to work on my Isuzu Rodeo and it was a Sunday. I needed some metric bolts and all of the local hardware stores are closed on Sundays (good for them!). But I was glad that I had TSC to go to so that I could get the bolts and finish the project.
I'll say that in general, I like my local hardware stores better, and I like Rural King better than TSC (but we don't have a Rural King), but I haven't had a bad experience at our TSC. I was pleasantly surprised two weeks ago when I needed some parts for my Troy Bilt trimmer. They had the right spark plug (which is kind of an odd ball - I've had troubled finding it before) and fuel lines, plus had a fuel filter I needed for another mower. I ended up spending about $30 (I bought other stuff too) but I got everything I went in after, and that's sometimes tough to do anymore.
Hope the store mentioned by the OP pleases them.
Good luck and take care.
