Depends what you buy and where from. Dai (my hubbie) invests in about 6 months worth of Assos and I think it works out at about e3.60 per packet. The more popular global brands tend to be more expensive. We usually order from Alison (supermarket on the corner) as we arrive and pick up just before we leave but others will take orders too. I think delivery day is Thursday for most of them......as you can probably tell this is a well rehearsed holiday activity (and I wouldn't even know how to light one up let alone smoke it !).
