The concept has drawn huge crowds across Europe because some shoppers abroad have found everything from collectable gold bars to rare Pokémon cards worth up to €2,000. The start-up said that it buys lost e-commerce packages, repackages them and sells them in their "original state", offering shoppers a "real-life treasure hunt" and said it prevents thousands of items from being destroyed. However, it's worth noting that after my visit, a huge amount of packaging was left behind.
