[/QUOTE]The propane tanks for grills are typically 20 lbs and if you exchange a tank for one that is full you will pay around 20 dollars. If you buy brand new they can be more spendy like 40 dollars. I am not sure why they are expensive to buy a brand new grill propane tank but I can only imagine it is because the demand for them is fairly regular so they can charge what they want. [/QUOTE]

New tanks around me are $45 and up. You can take almost any tank and exchange it for under $20 by me. now you have a brand new filled propane tank. Sell on craigs list for at least $40 --- $20 profit no sawz all required
