Recordjunkie

Nice place, right across the street from the theater, with quite a lot of heavy metal vinyl (they specialise in Kiss). Other than that there's a lot of used CDs, mostly pop&rock and mostly not that great stuff. But the prices are good (30-50 SEK) so you can make some finds! But then they have "good" used CDs too, which cost around 60-90 SEK. Apart from this they have lots of metal t-shirts, DVDs and stuff.

Worth a visit! (Well, if you just happen to be in Linköping, you gotta go there!)
