CO2: What do you pay?

I'm going to start this thread so that we can compare CO2 prices.
As an added bonus., You'll have a record of your purchase date and you can clock your lbs/month or whatever.

Please try to keep the questions to a minimum. If you have suggestions, ect you can PM me.

We don't necessarily need an itemized cost with tax and whatnot except if you have to pay for a Hydro test.

Let's start out with this format:

The question has been asked about how to tell if your tank is full or not.
Pressure varies with temperature, so it's not an accurate way to measure how much gas you have.
You need to look at the tare stamped on the tank. That is the weight of your tank when empty.
I have a 20# tank. The Tare is 11.33 KG or 24.97lbs. My tank is full when it is 44.97lbs.
