We've spent 5 weeks in Sweden this summer. Whenever buying alcohol (with more than 3.5%) the Systembolaget was the only choice, since the only one run and approved by the government.
That aside I must admit that these stores quite have a good selection of beer, wine and spirits and most prices are really fair. This store here was a bit small though and selection was limited. Staff was friendly and helpful. But just lacks the choice of the bigger shops, but there aren't any around in the area.
Also if you really want some upscale wine, we never found them in a Systembolaget. Don't know how locals would get these....well, online probably. But it's an ok store to stock up on some booze. read more
