I do what I can. Shop's own cheapest brand for most things. But I always buy non-caged eggs. Yes, a little bit more pricey, but that's one of the few things I won't skimp on any more. I home-bake as much as I can. Well, I have to - DS is allergic to most shop-bought treats. I organise recipes in advance, cost them out then see what I can cut down on within the recipe. What I can make stretch further. If I buy XYZ for this recipe, I can use X and Y the next day for another...

We also grow our own veggies in the summer: we only ran out of home-grown potatoes at Christmas time and still have some pumpkins to eat!
