About six months ago it was about £120 for the 2.5 (soon to be 2.75) of us, but that has crept up to about £150 and that is mostly basic's. We don't go for much named stuff, just supermarket own brands. Think thats why I got permission to dig up half the garden for veg

Also trying to shop for things in season from the UK, gets us down the local market, but you do pay for that...
