These are so hit and miss - sometimes they’re just everything is incredibly overpriced and sometimes if you show up late, you get an entire garage tools for less than the scrap value of the metal.
Walked back to my car shaking my head. Guess they didn't want to actually sell anything.
But others are run by professional estate companies; either they know they can get certain prices online (where?) or they do some form of scam where they overprice everything and when it doesn't sell they offer some "bargain price" to clear the house out.
