Cham118 1 | 1 29 Nov 2012 #1HelloAn important document has been sent from Poznan to my temporary address in Suwalki. The email I received from the sender says 'The letter was sent today to your address. It will arrive within a few days by regular mail delivered by the Polish Post.'How long does regular mail delivery usually take in Poland? Can it take longer than 3 days? Thank You.
