The United States Postal Service--that thing that puts L.L. Bean catalogs in your mailbox--is preparing to make massive cuts that will go into effect next spring. The changes will amount to around $3 billion worth of savings for the USPS and only mark the start of what is going to be a long cost-cutting process. A fully-detailed report on the reductions will be released tomorrow, but the Associated Press has some information on what to expect. SPOILER ALERT: Buying those "Legends of Jazz" Forever stamps didn't save the postal service.
