You do well to fit it into $150 per week for 4 people, I've been so tight over the last few months and yet it still goes over $100 for two and three cats.
Just veg is close to $50 or more... and that's not getting lots, it's painful shopping these days. I don't buy beef or lamb only a bit of chicken in the meat. Then add cheese (a bag of mozzarella and every few week a 1kg block cheddar, no camembert or specialty cheese) that another $7 (rounded up) for Mozz and $10 for cheddar, so now it's $60 and I've got veg and cheese, cat food $25, now it's $85. If it's a week for coffee $20/bread flour $11 or god forbid olive oil (usually wait for specials), that's not thinking about things like tins of beans, or cereal, milk, toilet paper etc etc. Damn impossible... the garden will make a difference though.
My pet hate when shopping is how the check out assistants pack the bags! Gggrrrrrr!!!!!
This is something that absolutely has driven me nuts for years!! I remember a girl dropping a tin on biscuits once... now I have all my bags and sort along the checkout with the bag in front of what's to go into it! I say to them 'it's sorted by bag' and all bar one has been very happy and think I do it to help them.
But if it makes it easy for them and me, I'm a happy person.
That one girl, I never go to her and if the manager ever pushes me in her direction I'll tell her why, not only did she flatly refuse to put things how I sorted them into the bags she mixed them up how she wanted... I was sooo angry I thought if I say a word I'll scream. It was so on the tip of my tongue to say, 'are you paying for these groceries because obviously you sorted how you want to be, not me the person paying'... boy was I mad!!
