Like I mentioned, grocery shopping in Norway can be a bit pricey, especially when it comes to meat and alcohol. The solution to this? Go to Sweden!*
Trondheim is conveniently located close to the Swedish border and there is a free bus that runs from Trondheim to Storlien. Just to give you an idea of how much traffic this place must receive from Norway, the bus is free and the shopping center seems like it’s the heart of the town (though calling it a town might be a bit of a stretch).
As you can see, Storlien is literally as close as you can get to the Norwegian-Swedish border.
The bus is quaintly nicknamed the fleskbussen or “bacon bus” because many of the people take the bus to buy cheap bacon. When I took the bus I used the Thorleifs Bussreiser system and called ahead (+47 72 55 33 94) to make a reservation on the bus.
Getting there takes about an hour and a half, and the bus leaves you about an hour to shop before returning to Trondheim.
As for prices, two kilos of boneless chicken costs around 120 NOK and beer is cheaper at about 70 NOK/six pack (and thankfully the stores accept Norwegian kroner). Other forms of alcohol are also cheaper, but for alcohol over 3.5% you have to order in advance, usually at least two days before your trip. In order to do this you have to go to the systembolaget website, select the appropriate shop (in this case Åre), select your desired alcohol, and checkout. An email with a confirmation code will be sent to you and you have to present this code at the store in order to pick up your purchases.
Funnily enough, it’s not just broke college students who try and take advantage of the cheap alcohol and meat in Sweden. About half of my bus was filled with non-college students, and the elderly man sitting in front of me actually asked if I would pretend to own half of his alcohol in the event that we were stopped by customs. To my surprise, there were no customs or passport control at the Swedish border, and as far as I could tell it seems like you can cross the Norwegian-Swedish border without having to do anything special.
*I’ve even heard of people flying to Poland to go grocery shopping since the total cost is still less than it would be in Norway, but I have not reached those levels of desperation.
