My weekly bill is always around 120-190 or so, this is for a family or 4 or 5. I think we do pretty well since we rarely ever buy takeout or rastaurant food, so it pays off (I'd say)
Since I've gone veg. a few years ago and with buying more of the healthier stuff the bill definitely goes up, it's sad but I'm finding certain things to be pretty well priced (especially more of the organic stuff that is coming in to almost all supermarkets here in Ontario) so I think it pays off a bit, shopping around is also a must, as well as switching brands or even supermarkets to find the better deals.
Come to think of it, it is so very high, especially since I don't even buy meats and a lot of "cultural/traditional" foods from the supermarket (those things I go elsewhere for)
Fish is a bit expensive too, salmon isn't too bad though, thank God since its a staple.
