That site is comically dead for some areas. I checked for prices in Zug some of them were last updated in 2017.
I’m reviving this in case anyone has anything else to share? With gas prices going up and up, it is becoming more important getting good deals.
Also, if you know of a cheap place in Romandie in Lake Geneva region in particular, I’m all ears. I can share my best known deal, in the outskirts of Fribourg: Eduard Waldburger SA.
