I feel like an idiot! I reread what decjr wrote and I guess I missread what he was talking about. He has a bunch of grill propane tanks to get rid of, not big ones for homes!!! That makes sense, sorry but here are answers to your questions:

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.
