The post office is so maddening, independent companies have been created to do the job for them. InPost is the largest, offering 3 points in the center. Take your mail to the window and they do everything the post office would, aside from making you stand in long queues, fill out piles of incomprehensible paperwork and opening international mail. A revelation. Also at Pl. Wolnica 14 (D-7, inside Fatima shop) and ul. Westerpaltte 3 (D-2, inside Biuro Turystyczno-Handlowe Magellan).
