A guy I worked with worked for the white van people. They were just selling speakers, but instead of having a store they went out in vans and pretended to have an “extra” set. Their pitch was “the last time this happened my boss took them home etc…” they’d have a fake paid invoice that had the price as $1000 a pair but would try to sell them for 300-400 bucks. They weren’t stolen it was just a scam to make people think they were getting a great deal. I live here, and people in this area love getting a “fell off the truck” deal
