Mel - after 7 months of having limited income due to me not working, and DH having enforced leave due to fires and the down turn in his work (which, yay, is finally starting to pick up when i need him home!) i know what it's like to be on minimal income and really struggling financially

DH and I can get away with minimal grocery money each fortnight if we make use of the slow cooker and bulk cooking. i know you've mentioned not having a big freezer, which isn't a huge help, but can i suggest you give it a go? and try to see what you can do. as i mentioned in my SC thread about my aunt with diabetes - we managed to cook just short of 90 meals for 240 - almost all of them in the SC. it's not great eating the same stuff over and over, but once you start experimenting with what you can make, you find a lot of stuff that is great and oh so tasty! and the best bit is, it's relatively simple to use. we make a lot of "versatile" type meals - stuff that you can eat today as something plain, next time you can make into something completely different (spag bol today, pasta bake late in the week - just freeze in between kwim?) - by packing it with extra veg, it's more nutritious, tastes better, and the veg is a hell of a lot cheaper...

as willow suggested - baking at home is heaps cheaper too - just make sure A isn't around cos he's not super helpful! i'd be looking for recipes that keep well over a period of several days so you only have to cook stuff like that once a week.
