Postal Info by acemj
This is the sign you'll notice if you happen to stroll by a post office. The post offices I visited in both Germany and Austria were extremely clean and efficient in appearance, but, just like in the States, there is often a long line.
If you're just mailing postcards, you're better off buying stamps from the vendor who sells you the postcards. They will know the correct postage to mail to most countries and then you can avoid the line and just drop your mail in a postbox. The postcards that I mailed all arrived back to the States in about 5-7 days.
