Phish you should always hedge and do some prebuy even if its not for the full winter supply.
And I would be very careful about prebuying a whole winters supply too. During the shortage a few years back some smaller propane companies went out of business and their prebuy customers had no legal rights to get their money back. IMO big suppliers have more resources especially if they have their own semi rigs hauling propane.
"Filled up at 1.03 today. So I am set til late december. That price is a nickle higher than 2 weeks ago."
Got ours filled at 1.01 from Hilgeys. Should be good to go until Feb. Knock on wood, my Generac 20 kW back up generator is powered by our tank and if/when the power goes out, the house has run 4-5 days on it.
