When you need to ship a package, which company first comes to mind? According to last year's Battle of the Brands non-scientific poll, an overwhelming majority said they favored United Parcel Service Inc. (NYSE: UPS) over FedEx Corp. (NYSE: FDX). Higher fuel surcharges, a weak economy, reduced domestic package volume, and a recent push from the U.S. Postal Service have impacted both of these international shipping companies in the past year, but Americans still want the same quality service at a discount price.

Let's take a look at a few changes since last year:

The US Postal Service Tries To Gain Ground

The largest player in the U.S. overnight package delivery business is attempting to increase its market share in the fast-delivery business next month. USPS is barely holding on to its 32% market share in the business, as FedEx and UPS continue to push the envelope at 31% and 25% market share, respectively. For the first time, shippers using Express Mail, Priority Mail, and several other parcel services will be able to get lower rates for large- and medium-volume contracts, according to the agency. Will UPS and FedEx need to cut their prices further to compete with the USPS?

In a record-setting one-day stamp auction that raised sales of $9.1 million, billionaire bond fund manager Bill Gross unloaded a series of early British stamps featuring a young Queen Victoria. The proceeds raised were donated as one sum to Doctors Without Borders; it was the medical organization's largest donation ever received in its 36-year history.

The top lot auctioned Monday morning included two items. The first was described as "the largest surviving mint Penny Black multiple still in private hands," consisting of 18 stamps, coupled with a strip of six stamps that were separated from the larger bunch. The two pieces together were ultimately sold for $1 million to an unnamed bidder. Attending the auction were bidders from the U.S., Canada, the U.K., France, Switzerland, Belgium, China, and Italy.

Gross said he began collecting the stamps in question around 2000, spending an estimated $2.5 million on them. While today's auction benefited a charitable cause, it also helped Gross gauge the market for collectible stamps. Mr. Gross is one of the largest U.S. collectors and estimates having spent between $50 million and $100 million on his collection (that's kind of a wide range, but who am I to quibble?).
