I shop once a week...usually Sunday. Our freezer is not that big so I can't buy lots of meat in one go. Anyway, I have lots of time so I can go to the grocery store any time.
We go at least once a week and generally we spend a lot of money on food. I think its okay though, as we eat good fresh foods a couple times a week.
I only grocery shop once a week and I always use a grocery list.
I actually go to the store once or twice a week because we want our food to be fresh especially when it comes to the meat and other things.
