A family in the United States have been lucky enough to buy a container for $500 to discover that millions were inside.
The story was made by Storage TV host Dan Dotson and his wife Laura.
He has confessed that a California woman had gone to him to tell him that her husband bought a container for $500, and inside found a safe.
"The first attempt to open the safe failed," he said.
"We got a second person to open the safe. When it opened it wasn't empty, it had $7.5 million inside it," he said.
He said the new owner came up with an offer of $1.5 million to return the rest of the money, but refused.
Containers in the U.S. are used by private firms as space to store goods and personal items for a monthly fee. When the tenant fails to pay the fee, the container goes up for auction and sold to the one who offers more.
