IKEA is actually a köttbullar and lingonsylts (lingonberry jam) distribution system so that us Smålänningar can get our fix almost anywhere in the world.
It's also one of the few places I can get herring too. The Poulsbo stuff that I like is seasonal so I have to go to Ikea for canned fish in the summer.
That I can buy furniture and kitchen tools is a nice bonus.
And while their selection is limited, it's one of the few places outside the Nordic countries and the Netherlands where you can reliably get salty licorice candy.
