Post offices are located in all major communities and are open from 8.30am until 4.30pm Monday to Friday. Domestic mail will generally get to the nearest post office within two working days, though a recipient living out on a farm might not collect it so quickly. For international post count on three to five days for mail to reach the UK or US, and a week to ten days to Australia and New Zealand. Anything up to 20g costs 35kr within Iceland, 50kr to Europe, and 75kr to anywhere else; up to 50g costs 45/95/135kr. International parcels aren't outrageously expensive - a 500g packet is 435kr to Europe and 900kr to elsewhere - but not particularly fast; ask at any post office about Express Mail if you're in a hurry, though you'll pay far more than for the normal service. Post restante facilities are available at all post offices; have mail sent to the relevant office marked "to be collected" in English and turn up with your passport. If you can't find an expected letter, check that it hasn't been filed, Icelandic-style, under your Christian name; it might help to have your surname underlined on the letter.
