I'm sure everyone is all too familiar with spotting some cool stuff and not being able to resist. I know I'm definitely guilty.
Fess up to the stuff you really shouldn't have bought but did! Let's be honest, the most likely outcome is that some of us will likely join you - but then you'll probably feel less guilty about it.
Fixed this for you
Is it wrong that I’m reading this conversation looking for things to impulse buy? 
I tend to overthink things, but I’ve impulse bought kits and bits off AliEx and Temu simply because the prices for interesting things are similar to impulse buying a coffee.
I wanted to semi-impulse buy a new battery electric lawnmower, but my SuperArtGirl blocked it with logic 
On pure impulse... almost every electronic accessory board - many that have never been built into anything. Some that I can't even remember what I thought I was going to do with them when I bought them.
I bought the Triplett ET30 Magnetic Field Detector pen because of a converstion here on e14. THAT was pure impulse.
Another angle grinder ($15). Pneumatic chisel. Pneumatic nibbler. 20 cheap multimeters - because they were $2 each. Chisel carving set. Vacuum desoldering station. Halicrafter amateur radio transmitter and receiver set. Cable winch. Large helping hands. 100w soldering iron. Two different types of wrench organizers. Trim router. Rotary tool kits (3 or 4 at least).
This is kind of depressing.
Well this afternoon it was "LEGO Classic Creative Space Planets Brick Box".
Currently less than half price in the supermarket and we are overdue another Lego-themed challenge from shabaz 
It sounds like healthy fun to me.
Hopefully I am over my addiction to buying multimeters...but I still have urges..
I have multimeters I have never turned on. 
Don't worry you can give me one of them
