What do you think would be a reasonable amount of money to spend on grocery shop per week? We are two adults and 3 young children. 2 of the children have school meals. We all have breakfast at home, dh takes a packed lunch and toddler and I have lunch at home. Cooked meal every evening. I really need to save money and food shopping is the obvious place I could cut back. I thought I would set myself a weekly limit and to try to stick to that but I'm not sure what would be reasonable . Last week I spend £170 which feels like a huge amount. It did include washing powder and there's still a joint of meat in the freezer to use.
