I'm the same way as OP. I'll go clean out my basement, find a load of old tech and just put it up in a bundle or sell it individually for dirt cheap. Likewise, I buy a lot of stuff like minimal wallets, micro-electronics like charging cables, dongles for my work laptop, phone cases. Just typically a lot of knick knacks or older tech stuff. There's a booming economy for old walkmans and cd players. Same thing with higher end audio stuff like older DAC's, speakers, amps. A lot of unique stuff you can't find on Amazon or elsewhere.
