Stamps for standard-sized letters and postcards up to 1 oz cost $1.20 in all countries. Prices for envelopes heavier than 1 oz, big, or irregularly shaped, on the other hand, are determined by the destination country's pricing category. These categories are unique to each postal service and vary depending on the level of protection against loss that particular service provides. The price of mailing a letter to Europe is higher than the rate charged to send one to Australia for example, because European letters weigh more than Australian ones of equal size. Price differences also exist between countries within Europe because they handle postage differently. For example, Austrian letters weigh less than German ones of equal size, so Austria has lower rates. Within Europe, there are two types of postal services: national and international. National services include Germany's Deutsche Post, France's La Poste, and Italy's Poste Italiane. International services include British Royal Mail, which handles both domestic and international mail, and Russia's Post Office Department, which only handles international mail. It is cheaper to mail a letter to an address in Europe than anywhere else in the world. The rate for first class international letters up to 1 oz is $11.80. Envelopes are extra. There are four ways to pay for your letter: cash, check, credit card online, or by phone.
