Two $6 dollar tools you should own

This 60-piece precision screwdriver kit is $15, but if you use discount code ORTBHA221 at checkout it's just $6. I have a nearly identical set and it comes in handy at least once a week. And I have this digital multimeter, which I use every time I work on an electronics project. It's usually $8, but if you use code 8IXIP46Q you can get it for $6.
