Every other month I travel to my friends and “extra family” in southern Sweden, and usually by train.

With the SJ Prio card from the Swedish inter-city train-company SJ I can get one (1) point for every one (1) SEK I spend on trips. You can spend points on additional trips and services.

For 2000 I can get a sandwitch on the train, if I want.

That means that a sandwitch is worth 2000 SEK (≈ $335).
