I buy Organic fruit and veg boxes and enough meat and fish, milk and bread to last 4 of us for the week days from here .
I have a two week circulating order which comes to around £56 per week. That gets us loads and loads of veg and fruit, fish cakes, fish pie mix , eggs, trout fillets, gammon steaks, sausages, lamb neck fillets, minced beef. Mince, fish cakes and eggs come every week everything else is rotated over the fortnight.
On top of this I then shop locally for weekend food but only the protein bit, the veg and fruit keep us going for the full week. I also need to buy kidney beans, tinned toms, fruit squash, rice and pasta - all organic (usually another £20-30 a week).
So it is quite expensive but that is mostly due to being extravegant at the weekend more than with the cost of the weekday meals.
BTW - we are a family of 4.
