Our model is: Sodastream Source.
CO2 costs: 60 liters of CO2 @ $20 = 0.33$/liter (Canadian Tire, ignoring $16 CORE fee)
Syrup cost: 6 – 10$ / bottle makes 35 liters seems to be normal. Assume 30 liters, and 8$, so 0.26$/liter
Total cost for a liter: 0.33 + 0.26 = 0.59/liter
Pop: 6x710ml = 4.26 liters @ $3.50 = 0.82$/liter
