I need to buy a propane tank for my gas kettle. Other than the small tank I bought for my performer then had filled this will be my first full sized propane tank purchase ever. I'm going to home depot today to pick up some KBB and figured I get a tank while I was there. Should I buy and empty tank and have it filled elsewhere, buy an empty tank and immediately exchange it for a full tank, or should I buy on of their already filled tanks?
Prices:
Empty tank: $29.97
Full tank (no exchange): $48.22
Tank Exchange: $19.97
Obviously buying the full tank saves me $1.72. I have no idea how much LP costs at gas stations, so I'm not sure if I'm better off getting the empty tank and having it filled somewhere, or just getting the already filled tank.
(MODS: Just realized I should have posted this in the Gas Grill section....feel free to move it.)
