Our FOOD only bill is about £40 to £60 a week all in, which includes our food, fruit and veg. However what we actually spend with Ocado is more than this as it includes cat food (they will only eat expensive food), wine and beer, cleaning products, toiletries and so on, which usually doubles the bill - the cats cost £20 a week on their own but they are really excessively spoilt.
The bill is less in the summer because we grow our own veg, and now we have our own eggs we are spending a bit less as I can now bake all our cakes, biscuits and other stuff that needs eggs. I also save because I bake our own bread. We never buy ready meals - it is all made from fresh ingredients, which keeps the bill down.
I could get it cheaper if I didn't only buy organic/free range things.
I only do the one Ocado shop, have a fortnightly organic vegbox delivery in the winter only, and just top up with a few pints of extra milk from the local shop.
What we really do try to do, and want to try to do more of, is to buy as much local and seasonal food as we possibly can, and grow our own too.
