imageCongressman Darrell Issa (R-Calif.) is proposing that the U.S Postal Service end door-to-door delivery in favor of neighborhood "cluster boxes" — the kind you might see in a condo complex.

Issa says the change could save the Post Office $4.5 billion a year.

(Contrary to popular belief, the USPS does not receive federal funding. All its money comes from postage and delivery sales and services.)
