We spend on average $120-$150 a week, that's just DP & I. Like Nai, I also do a meal plan each week, make a list and stick to it! I buy things such as toilet paper and washing powder when they are on special, even if I don't need it that week. Makes the grocery bill higher that week but cheaper over the year.

The main things included in my weekly shop are fresh fruit and veg, meat, milk and tinned things like baked beans, diced tomatoes, dried pasta, rice, etc. Although I tend to stock up on those things when on special so they are always in the pantry.
