Any cool life hacks to save money, have fun or anything that others might not know about, except the SBB half-fare ticket? I’ll start with the TooGoodToGo app, which basically gets you restaurant food for much lower prices that you can pick up short before the stores close.
not really a life hack, but most of the bigger stores buy their “fresh” stuff for the weekends, so if you shop on monday/tuesday, you may get a reduced price on vegetable, meat, etc.
