food shopping bill

who knows they spend way too much on food shopping and could cut back if they shopped around? whats everyones tips on getting good quality value for money food?
since i went on maternity we've near enough halfed our food shopping bill and thats just but shopping for fresh fruit, veg, salad and meat twice a week at the market and local butchers. when i go back to work im not going to have as much time to shop and prepare fresh meals for us every day though.

i buy a lot from iceland now days as its a lot cheaper for frozen food
