The postal service will be the primary shipper for all government owned companies, and the government itself. In addition, the Kaldus Postal Service will also deliver standard envelopes including priority and certified mail. Price will depend on weight in ounces. While this will be different when compared to grams, the goal for this is to make postage (especially the first ounce) as affordable as possible. Postage is always defined as a price + a rate per ounce. The base price will be used for post cards, whereas. the rate per ounce is the variation. In case one needs to know, 3-4 sheets of paper can be sorted in the first ounce. This means if someone uses a printer, and prints on both sides of the sheet, they can provide a lot of details in a single letter.
