On April 30, the US Post Office will have available for purchase books of 20 First Class Postage stamps called "Adopt a Shelter Pet." The post office, in conjunction with Halo Pet Food, is helping to save the lives of millions of unwanted pets. When you buy a book of the stamps, you'll be contributing funds to the 'Stamps to the Rescue Campaign.' You buy the stamps and Halo will buy food for one million shelter pets. The dogs and cats on the stamps are adorable and you'll be helping to keep some unwanted and unfortunate animals alive until they find their forever families. You can pre-order the stamps now through USPS.com or pick them up at your local branch when they arrive at the end of this month. Buy something as practical as a book of stamps and in the process, do something wonderful for an animal who deserves a happy life. It doesn't get any simpler than that.
