Have you ever purchased something through a bank and or police auction? Here in the US banks and police all over the country will put up items for auction. This could include old evidence that's no longer needed, repossessed cars, houses, and properties. You can also buy used equipment, tech and more from these auctions. I never invested in anything like this, but I imagine you can buy a ton of great and usable things through these type of auctions. Have you ever purchased something usable? Or invested to sell some of this stuff later?
