I can't work out how much we spend right now, DH is o/seas so I"m buying less food but spending more getting convenience things I would not normally dream of buying. Just wanted to suggest that if you bulk out your meals a bit with extra veg, rice, pasta, etc, then every 3rd or 4th night you can have a leftovers night - it saves money when you do this a couple of times a fortnight. Plus you don't have to think about what to cook!

Also, scratch teas are good - you know the evenings when you can't really be stuffed so you make an omelette, or open a can of soup, or make cheese toasties. Much cheaper than running out to the shops to get something. For this reason I always make sure i have things like eggs, baked beans, soup, noodles and jar pasta sauce in the cupboard - not as a planned meal but for those nights when it's too hard to think what to have!
