My condolences. I'm on propane as well for heat/hot water/range. Took over the tank lease from the previous owner with Amerigas and it was reminiscent of dealing with a cable company. The worst cable company. Trying to lock you in to various plans for extended periods of time, auto renewals, etc. I was looking for the plan that was "pay a fair market rate upon delivery". They weren't keen on that. Eventually I got fed up and spoke to Advantage propane who stated that their max per gallon price, at the peak of some of the shortages a few years ago, was still less than the lowest rate I'd been paying with Amerigas. Spoke to a manager at Amerigas, at length, about my issues with them and he eventually lowered their rate by $1/gallon. So, you were in a position to offer me something that would save me something on the order of $1k per year, but didn't because I had to threaten to leave and go through all of the negotiating BS that nobody wants to deal with first? That's exactly the reason that I left.
Been happy with Advantage. Still bitter about Amerigas. They went so far as to take me to collections over a renewal fee that they'd stated multiple times had been removed. Hate those guys.
Anyway, hope your experience is better!
