I must admit that I haven't really noticed, but I'm reliably informed that everything is going to get much more expensive, and in many cases already has.
Maybe I have subconsciously shopped slightly more wisely than usual, but I've easily been able to stick to my sub £100 weekly spending on food and wine.
Being the cook of the house (which I enjoy) I am able to keep tight reins on my spending, and stick to meals that are both reasonably priced and tasty. I don't buy pre-prepared meals, or takeaways, and I cook from scratch every day.
As long as food continues to be available, and we are not obliged to drink from ditches or eat our pets, I for one shall now be reducing my spending, eating veggie more often, and trying to economise. There is great pleasure in producing really good tasty meals for little money; I recommend it to everyone.
