WASHINGTON — Allowing the Postal Service to deliver beer, wine and spirits is high on his wish list for raising cash for his financially ailing agency, Postmaster General Patrick Donahoe said Thursday.

In an interview with The Associated Press, Donahoe also endorsed ending most door-to-door and Saturday mail deliveries as cost-saving measures for his agency, which lost $16 billion last year.

Donahoe said delivering alcohol has the potential to raise as much as $50 million a year. He mentioned how customers might want to, for example, mail bottles of wine home when they tour vineyards. Donahoe said his agency has looked at the possibility of using special boxes that would hold two, four or six bottles and ship for a flat-rate to anywhere in the country.

“There’s a lot of money to be made in beer, wine and spirits,” Donahoe said. “We’d like to be in that business.”

The Postal Service says mailing alcoholic beverages is currently restricted by law. Customers are even told to cover any logos or labels if they use alcoholic beverage boxes for shipments.
