I agree with general responses, for a cheaper shop. You're shopping at the wrong places. It may be more convenient for you, but if you're not willing to put in a bit more time and sacrifice you aren't going to save money. Different shops are better for different things in terms of prices.
Feel free to give me a break down of your shopping list and I'd be happy to offer pointers.
here is a response I made in another thread of how I can quite easily have a well balanced and varied diet at around £20-£25 a week. It shows what I buy, where I buy and how often I generally buy items. As well as a few meal ideas related to the list.

Edit: Just spotted a previous thread of yours "scared to shop in aldi" and a couple of your responses . It's very clear now your food bill is so high because you're a brand snob. And I don't mean that in a nasty way, it's just very clearly true. You'll never save money until you get it into your head that the brands you are used to and the stuff in the prettier packaging is rarely any better than the non branded or lower brand stuff...and it's really not worth the extra money. It's illogical spending.
