I never pay for a refill, I just go to our local fire extinguisher supply company who will give me a free exchange every time.
They supply hundreds of businesses like banks, hotels etc. The cylinders have a certain shelf life but, the company always collect & replace them 6 months before they reach that date. I get given the old cylinder before they are decommissioned.
I once went inside their store & workshop, there were hundreds of full C02 extinguishers waiting to be emptied & decommissioned!
i do however show my gratitude by buying seasonal gifts like a couple of tins of quality street at Christmas or a couple of Easter eggs a couple of lobsters etc .... so i guess it is not really free!
