Nitrous Price
If you still have juice, they will charge you 4 dollars on a top off.
10lb bottle... 28.00 dollars at a couple of shops here in dallas,tx.

There is a place in Washington, NC that charges $2.50/lb! But that's an hour drive for me.
There are places that are $5/lb in my town, but I don't care to mention them.
