How much does it cost to re-fill (or exchange) a propane tank?!
Like the kind you use for a grill.
Answers:
Between 15 and 20 bucks.
All depends on where you live! Where I live it is actually a little bit cheaper just to exchange your tank for a new one rather then get your current one filled up. Right now propane is outrageous so I would shop around and see who has the best price.
