Timely reboot. Let me tell you my saga with Amerigas. We have a smallish tank 120 lbs I think. We use it to run a propane fireplace in the house. Tank is owned by Amerigas. We go through one tank per year so we never make the minimum and we get charged a rental fee for the tank. Tank is probably 10 years old. I just called for my annual refill and they quoted me $4.58/ gallon to fill our tank! I said no I want 2019 prices please. They couldn't explain why it was so high. So I discussed my options with them: bend over and pay their price, buy the tank for $225 + tax, or have them come remove the tank for $135. Still deciding what to do.
PS just filled up our 500 gallon tank at cabin in PA for 1.56/gallon
Remove the tank yourself and drop it off. It's nothing more than turning the gas off and disconnecting the line. Put the $135 towards a tank from the links I posted above, or below.
If you want smaller tank(s) 100lb tanks can be had anywhere. HD/Lowes sells them new, or used below.
