CPU stands for Contract Postal Unit. That means that we can do almost everything that the Post Office does at the same price, but a portion of your purchase stay here in downtown Washington.

Since we are an independant contractor for USPS, we earn commission. Therefore, when you purchase stamps here 9% is reinvested into downtown Washington and packages reinvest 20%!
