There are two shopping centers in Helsinki center, right next to each other.
Kamppi (surprisingly located in the Kamppi district) is a combined shopping centre, nightlife focal point and transportation hub in the dead centre of the city. Kamppi features a large variety of small-to-medium sized shops, bars, restaurants and other facilities.
Forum, opposite to Sokos department store, is more clothing-oriented than Kamppi, and also features an affordable food court in the basement level.
Itäkeskus shopping centre is one of the largest shopping centres in Northern Europe. It is in the eastern suburb of Itäkeskus, very easily reachable by 15 minutes on the metro.

Best places to do some shopping are found right in the center of Helsinki. Stockmann is the most famous department store, located in Mannerheimintie (really hard to miss). Here you can find anything you need from shoes to vacuum cleaners and computers. It’s an upscale place with rather high prices and brand products – but the service is top level as well. Be sure to check out the newly renovated grocery store in the bottom floor!
Near the railway station is another department store called Sokos. It’s smaller and less glamorous than Stockmann, but it’s still worth checking out.
Electronics, music, movies
For discount priced CDs, DVDs and Blu-rays, go to Anttila (one found in the tunnels of railway station). It also has a wide variety of clothes, make-up and cosmetics.
Two major book stores are Stockmann’s Academic book store (next to the Stockmann department store) and Suomalainen kirjakauppa (opposite to the railway station). For cheaper books, go to Kirjatori (railway station tunnels).
