I bought an automotive tool set from Wally-world a few years ago for $8 on clearance. One night soon after, I had to replace the starter motor in my big truck (Chevy 1-ton) on the side of the road. I used only what was in that kit, and did it in about 30 minutes (once the new starter was brought to me.)
The next day, I went back and bought all the kits they had left. I have one in every vehicle, both work and personal, and have given a few as gifts. I still have two of the kits unopened.
They have full sets of 1/4" and 3/8" SAE and metric sockets, a ratchet handle and extension, multi-bit screwdriver, 24 screwdriver bits, needle-nose and slip-joint pliers, wire-stripper, battery-terminal cleaner, feeler gauges, rubber mallet, electrical tape, crimp terminals, anti-freeze tester, etc.
Now, there was a great bargain in tools.
