CAPE CORAL, Fla. - Do you have one of those white post office bins in your garage?

If you do, you're breaking the law. It's federal property and the post office wants them back.

The post office says people receive the bins and then use them for storage. If you do have them, you won't be fined or face charges. Postal workers are just urging you to return them to your local post office.

Each bin costs $4, and if people keep them, postal workers say you could see higher charges to offset the cost.

Fran Rounding of the U.S. Postal Service says, "We do need them back. We do use them daily for all of our mail. Our flats go in them so we reuse them over and over and over and they are very important to our operation."
