I keep some small tanks (100, 40, 33 and 20 pound tanks) for shop use,,
such as a mini forge, a couple infrared heaters,,
No home delivery would fill the tanks smaller than 100 pound, the smaller ones have a different fitting.
I took the tanks to a local ACE hardware I got 59 gallons for $3.29 per gallon.
When I got home, I did a back calculation comparing my purchase to the "BLUE RHINO" pre-filled tanks.
My final cost was exactly 1/2 the cost of buying pre-filled BLUE RHINO tanks.
PLUS,, since BLUE RHINO puts so little in each tank, I would need to move 17 tanks
(some Blue Rhino resellers even charge more than what I calculated with)
I thought it was bad enough getting 7 tanks to fit in my truck,
let alone having to pay BLUE RHINO $388 for that much propane!!
