I have a surplus of random electronic components, most of them are reels (spools) of resistors, capacitors, diodes, FETs, ICs, connectors and so forth. They are all new, unused, and while I should probably just throw them out, I really don't like to throw out perfectly good stuff!

So, if you can use it for any purpose, $20 takes all 5 boxes. They're all labeled and marked with quantity and what it is.

You could make some fun art/STEM projects, resell the parts, melt them down and extract the metals... the possibilites are endless!
