I think... For the 6 we've just had done, it was $10 per window for argon. That's about right. Argon adds (or rather, subtracts) about 0.15 in U value - so a window of say 2 sq.m. would have a payback in Melbourne for Argon alone of 3 watts 24/7 @ 10 degrees Celsius temperature difference. Taking 333 hours to make 1 kWhr @ 20 cents* and 16,650 hours to recoup the $10. That's 2 years to repay $10... not bad. Argon does deplete and will have halved in 20 years. *I use 20 cents as an easy number to represent the cost of 1 kWhr, check your own account or convert from gas at about half that cost (so payback would be 4 years with gas heating).
