I don't know where you buy tools, but, the professional tool trucks are ultra-expensive. Also, consider that pawn shop prices can be negotiable. I think there is a better deal to be had from mom & pop pawn shops versus chain or franchise versions like Cash America or EZ Pawn. There is nothing wrong with Harbor Freight per se, I have one the digital vernier calipers that is plenty accurate and they are less than $20 new that I use for quick stuff ( I bought it for around $5 with some other cooler stuff at the pawn shop!).
Pawn shop inventory can change daily as well.
I just want to share, I am not a tool snob, I have all sorts and brands, I needed an impact wiggle socket, I went to the pawn shop and dug out a whole set, not the same brand, but all the sizes....they were marked around $15 each, I think I ended up paying closer to $5 or $8 each because they made it a package deal. A pawn broker can smell a tool snob a mile away, so if you are always just looking for Snap-On or Mac or Matco only....you are gonna pay a premium. So now, every time I go in there, I buy stuff, extra, like I needed a shop hammer (handle broke on mine) bought a 36" long transmission removal style 1/2-to-3/8 extension, said digital caliper, three misc hammers, a couple of chisels, and a tape measure... for what they had the extension marked as a package deal, the joke is "the more you buy, the cheaper it gets!" I culture this relationship....I go and buy stuff here and there, like one of those HF transmission jacks, I got it for $40 along with some other stuff. The theory is, you are a good customer, you will come back for more, along with, a pawn shop normally has already made money of the items for sale (they were in pawn) and they are taking up shop/store space.
Now, the pawn shop I deal with, has been in business in some form or another since 1912. Its totally old school, guns, tools, some hunting/camping stuff, jewelry and some musical instruments, they don't take plastic...they deal in cash, do the same with whatever one you go to*. I started going there for guns only...it escalated...I take people there to find stuff...I refer people there all the time having them use my name, when I went to roof my dad's house, I went in to buy a couple of roofing nail guns...they let me borrow three, as long as I would clean and oil them up before I returned them...I ended up buying one.
My depth gauge, piston ring compressor, shop heater, numerous wire dikes, crimpers, pliers, wrenches, tons of sockets, brake spring and bleeders... tons of stuff, all has pawn shop stickers or numbers.
