Rip-Off pricing

How can CO2 gas be this expensive? On average you can get a 9kg LPG cylinder refill for around R130.00. A CO2 cannister from a Sodastream vendor is R150.00 per 400 gm refill bottle, so LPG gas is cheaper than CO2??? Go figure what a ******* this is. Suremix 100 is R390.00 (retail for a refill) of 10L of CO2. ie R39.00 per liter or R15.60 for 400ml, where does the other R134.40 go to?

Even if you, Sodastream, made R20, your vendor made R20 and R20 for transport, you still have a long way to go in justifying these prices. Thumbs down for taking advantage of the consumer.
