We are currently getting excellent service from our internet provider. We stayed with them through some difficult times (On of their towers was sabotaged) and now have a favourable rate on more bandwidth. Which in turn allowed us to get rid the satellite TV service which gave us the few channels we want bundled into overpriced packages with channels we never watch. The four streaming subscriptions are much cheaper.
Insurance, we did switch, twice in the last 20 years. As for propane, we have two suppliers (separate tanks) and top up whichever offers a better rate each season.
